My cat is having spasms constantly. His whole body seems to be affected. He is only 1! It's been a month now, and no one knows what is going on. He is still eating/drinking/using the litter box/playing, but every time he lies down, he is bothered by spasms! He is experiencing random bolts of energy accompanied with frustrated cries, and he purrs too often, which worries me that he is in a lot of pain. He has had blood work and x-rays, but nothing has shown up as abnormal.

He is currently on medication for Epilepsy, but it is not helping at all. I think in fact, he has become worse. The spasms started in his back legs, and now his whole body is involved. He walks stiff legged, as if he does not want to bend his back legs - he also sleeps with all four legs stretched away from his body.

When he is playing, he lies down every few minutes to rest, and he often pauses to stretch his hind legs. He is having a hard time using his back legs - they tend to slip out from beneath him when he's running, jumping, or climbing. His eyes are a bit watery, and he tends to close his left one quite often. He has a weird look in his eyes like he's confused or upset.

He may be throwing up/or having bowel issues - I have found spots on the floor and have been unable to determine if it's vomit or feces, (it may belong to one of my other cats. I am uncertain because I have not seen any of them throw up).

I am terrified that he is crying out in pain, and waiting for me to help him, and wondering why I'm not. I'm also horrified that he is slowly dying, and all I'm doing is watching him, because no one seems to be able to help him! I'm so worried and sick over this!

And just so you know, he is an indoor cat. Here is a video, showing the spasms that he has (awake or asleep).

Hello, welcome to catsey.
What's your cats name ?
I'm sorry to hear about the problems he's having, has he always been like this.
I too have watched the video and the twitching looks like he's dreaming to me.
I hope you get to the bottom of whats going on

hi, welcome to catsey. i've looked at your video and the other one also. i thought something to do with hind leg degeneration so i googled it, and came across this which sounded similar to your story:

Hereditary myotonia has been seen in a small number of cats. No particular breed appears to be over-represented and all affected cats in one report were related; an autosomal recessive mode of inheritance is suspected. It is a disease of the muscle that results in continued active contraction of a muscle after the cessation of voluntary effort and is characterised by muscle spasm and stiffness. Affected cats walk with a stiff awkward gait. The limbs are abducted (feet turned outwards) when walking because of poor flexion of proximal limb joints. There is widespread hypertrophy (increase in size) of muscle groups. The stiffness is worse on awakening and in cold weather, but improves with exercise. When affected kittens are startled, they may stiffen and fall into lateral recumbency (onto their side) with their legs extended. Spasm of the eyelids and facial muscles occur frequently when they are startled. Their jaws cannot be opened fully and there is sometimes difficulty eating. Diagnosis is made by performing an electromyogram (EMG) and/or taking a muscle biopsy.

and this is the website i found it http://www.fabcats.org/breeders/inherited_disorders/musculoskeletal.php

He does it when he is awake too, so no, not a dream.

Wow thank you! I will definitely look into that! That sounds like a major possibility! Thank you lynz85!

yes i think Lynz may be onto something there. If i were you i'd print out the article and take it to your vets.

Well after many tests, saying that there is nothing wrong with him, the Neurologist said that it's most likely FIP which is difficult to diagnose, and a death sentence. He said the only way to know for sure that it's not something else, is by giving him a brain fluid analysis, and he said that is a risky surgery, and there is a large percentage of animals who die during it. So I think I have no real choice but to stop searching and let him live what life he has left, stress free? What if it turns out it's not an infection, and he died on the table for nothing at all? And the vet said that it's unlikely that if it is an infection in the brain, that we'll be able to help him. There's always a chance, but unlikely. I'm so horrified by the situation. I don't want to ruin what life he has left by looking for a cure and stressing him out, when the likeliness is grave:( I hope I'm doing the right thing:(

These were the results of the tests...


Lycan

1 Yrs. 2 Mos. Shorthair, Domestic Neutered Male 5 kg (05/24/2012)

Thank you for bringing Lycan in for examination yesterday, May 24, 2012. At the time of examination,
Lycan was receiving phenobarbital (15 mg tabs) 1/2 tablet once daily.

After completing my distant, physical, neurologic, orthopedic and dilated ocular fundic examinations, the
following were revealed:

• Lycan was bright, alert, and appropriately responsive to external stimuli
• Lycan's body condition score was approximately 5/9
• Lycan was reluctant to move in the examination room to fully evaluate his gait. Lycan was shy and
nervous.Of the little movement I did observe, I could not appreciate and gait abnormalities.

Lycan's body temperature was 39.3 deg C, his heart rate was 200 bpm, no heart murmurs or
arrhythmias were detected. Femoral pulses were present in both hindlimbs and of appropriate
character, there was no evidence of pulse deficits. Mucous membranes were pink with CRT < 2
seconds. No observable oral ulcerations or masses were present. Head, neck, and body were
symmetric with no abnormal postures. Lycan had full voluntary range of motion of his head and
neck. No pain response was detected upon dorsal palpation along his spine. Thoracic ausculation
revealed increased breath sounds though it was difficult to discern if these sounds were referred
from the upper airways. No findings consistent with peripheral lymphadenopathy. No masses
detected on abdominal palpation. Lax patella bilaterally but unable to luxate.
• Neurologic examination did not reveal any significant findings. Cranial nerve examination was
unremarkable. Tactile placing was present and appropriate for all four limbs. Patellar, cranial tibial,
and sciatic notch-stimulated reflexes were present and appropriate for all four limbs. Voluntary tail
movement was present. Anal reflex was present and appropriate.
• Orthopedic examination was unremarkable.
• Dilated ocular fundic examination unremarkable. No evidence of keratic precipitates or iridal
discolouration.
• History from you included a description of progressive clinical signs beginning with periodic eyelid
tremor, to stretching, spasm of hindlimbs at rest. Clinical signs began to involve forelimbs. Video
recordings evaluated by me revealed lycan having hypertonicity of hindlimb during walking after
episode, difficulty jumping up fully onto objects, hypermetria of left hindlimb. Lycan has been alert
and responsive during these episodes. Clinical signs have progressed in frequency and severity. You
indicated that last night, Lycan abnormally began wrecklessly running around the house for
approximately 2 hours(atpyical for this cat). You also indicated that he was vocalizing more
frequently. You indicated that you have not detected any vermiform skin/muscle movements.
• Lycan's clinical signs have worsened despite phenobarbital trial by your veterinarian.
• Lycan's appetite has, at present, remain unchanged.
Given my clinical examination findings, and taking into account Lycan's clinical history and video
recordings of his episodes, I am concerned that he has a disease process involving multiple regions of
his central nervous system. It may be possible that he has primary muscle disease also, however,
though this may not account for his seemingly recent change in behaviour (i.e. wrecklessly running
around and increased lethargy).


Given this, and taking into consideration Lycan's clinical history and age, etc, the following disease
processes are considered:

• Infectious disease (e.g. FIP (feline infectious peritonitis), FeLV/FIV, Toxoplasma, etc)
• Inflammatory disease (e.g. immune-mediated disease)
• Neoplasia (i.e. cancer -primary vs. secondary)
• Metabolic disease (involving whole body and brain, and/or muscle)
• Myopathic disease (primary vs. secondary)
As such, I recommended the following diagnostic work-up:

• CBC, serum biochemistry, urinalysis
• Infectious disease testing (FeLV/FIV testing, Toxoplasma testing)
• 3-view chest and abdominal radiographs (x-rays)
• CT of brain and cerebrospinal fluid collection and analysis (pending results of above tests)
• +/-electrodiagnostics of nerves and muscles +/-muscle and nerve biopsy
After discussing my clinical examination findings, the rationale behind the diagnostic plan, and the
various disease processes being considered, you elected to pursue non-invasive testing first. You
understood that diagnostic testing is a process and that in completing these diagnostics we may not have
a definitive diagnosis (esp. with regard to FIP). You also recognized that without performing appropriate
diagnostic testing and determining a cause for Lycan's clinical signs it is impossible to offer an accurate
prognosis.

Chest and abdominal x-rays did not reveal any significant abnormalities (see radiology report).

FeLV/FIV tests were negative.

Urine was unable to be collected (bladder too small for collecting urine)

CBC and serum biochemistry did not reveal evidence of underlying systemic disease (not always present
with certain diseases involving the central nervous system). There was no evidence of active muscle
disease (e.g. no change in CK enzyme).

Toxoplasma test results are thought to be available early next week.

At this time, I recommend waiting until we have the Toxoplasma test results available, then bring Lycan
here for re-examination, and have a discussion of what, if any, further diagnostic tests you may want to
do further.

As mentioned, I am suspicious of Lycan having infectious or inflammatory disease. One of the
considerations is a disease known as Feline Infectious Peritonitis (FIP). Please review information
provided regarding FIP.

Please monitor Lycan for any change in his behaviour, how he moves, etc. Please try and video record
these behavioural changes. It is not uncommon that patients, especially feline patients, to act differently
in the clinic environment compared to how they act at home.

Please seek immediate veterinary attention should Lycan's condition suddenly deteriorate or if you have
questions or concerns about Lycan. Be certain to take this information with you should you seek
veterinary attention.

It has been a pleasure meeting and working with you and Lycan. I have sent a copy of these discharge
notes to your veterinarian and I have also spoken with her personally.

I am so sorry to read this about Lycan but on a possitive note you have done all the tests you can possibly have done to determine what may be happening with him. I have a few articles on FIP but none of them mention anything about convulsions, what ever the outcome I am sure you will make the remainder of his life as comfortable as you possibly can. My thoughts are with you both xxx.

The above site might help you to understand the condition a little, should it be FIP. x

What a detailed report from your vet, I'm impressed at their diligence. However, that doesn't take away that Lycan is possibly quite unwell :(

I agree that you have to draw the line at invasive procedures, after all the poor cat doesn't understand what's happening and we have to balance full diagnosis against risk and distress.

Wish you much luck and hoping that Lycan is able to live a good quality of life for a good while yet.

Thanks. I wish I knew what was wrong. The Neurologist doesn't really think it's FIP now because there are still no signs, from the second round of tests. He's very confused. Usually with FIP there is bleeding behind the eyes, and red flags in the bloodwork. Still nothing. But something is terribly wrong, and I don't know what to do! My poor Lycan! I've been reading up on Hereditary Myotonia, and it fits the profile, but the Neurologist doesn't seem to think so. Now I'm worried that his lungs are malfunctioning. Maybe that's why he is spasming - his lungs are contracting uncontrollably. I don't know. I want to help him but I don't know how. I feel so lost.

Oh dear this all sounds very distressing both for you and for Lycan. I sincerely wish there was something we could say or do to help, we are all thinking of you both xxx

I was thinking Lycan may have had slight neurological damage from birth, but vet has ruled that out. I know you desperately want to find out what it is and future ramifications...but the main thing is for now it doesn't seem to be really worrying him and he seems to be breathing ok. He actually looks an otherwise healthy cat.
Sounds like you are doing all you can for now, try not to worry too much in the interim, cats are very good at absorbing our concern and it can affect them.

Update on Lycan:

We still we have no diagnosis for Lycan. The good news is: THE FULL BODY SPASMS ARE GONE! Perhaps the phenobarbital (for seizures) has helped, or maybe it's a coincidence. But he is still having problems. His back legs bother him a lot and he seems edgy. His tail has developed this weird "shiver" when he gets excited. I have never seen a cat's tail do that. He also experiences small twitches in his face and has difficulty walking/jumping. But he's happier than he was, because he doesn't have the spasms to keep him up a night. So now he can sleep peacefully. Thank ******* god. But yeah, we did more and more and more tests, and the only out-of-normal results we've come up with is that he has an extremely high Corona Virus Titer Level, which supports but does not prove a diagnosis of FIP (cats can have high levels and never get FIP), and his Thyroid levels arel normal, but a little low for someone of his age. He has been checked for everything, including Hyper and Hypothyroidism, but now I'm wondering, though rare, if he may have Hyperparathyroidism. There's so little left to check, unless we do a spinal tap, which seems extreme and dangerous, considering the results of disease discovered through spinal fluid is usually grave and incurable. He's been biting/licking at his right back leg (the one he seems to have the most trouble walking with) and he has some cuts on it - we don't know if this was a rough-play injury that he keeps bothering so it can't heal, or if it's a lesion that has developed randomly, which also supports an FIP diagnosis. He seems less interested in food and water than he used to be. He lost weight within a two-week period, but then he gained some back, so we're not sure if that is a factor, or if he was just eating less because of the hot weather. This is very frustrating.

I have spent so much time researching cat diseases and symptoms, and have used many resources, including a Veterinary Encyclopedia. Lycan is an anomaly to Medical Science thus far. He is not alone, because I've found various other cases of cats with idiopathic spasms, and they never received a diagnosis either. Unfortunately, a lot of these cats ended up dying prematurely due to lung/heart/blood issues, so maybe there is something to look into there. I have checked his heart/lungs/blood/liver/kidney/thyroid/etc. But still no conclusive results. Something is hiding somewhere. I hope I can find out what's wrong before it is too late. It is unlikely, but I have to try, while keeping in mind that he may in fact have FIP (which can have neurological signs), which means he may be dying, so I should be careful what I'm willing to put him through (less stress is best), I want him to be happy and stress free, even if that means I may not discover the truth. It is a very difficult situation.

I must admit, reading the description made me think of toxoplasmosis, as it sounded similar to our Mustard. Is he hypersensitive to stimuli, how is his eyesight.

Both toxo and FIP are hard to diagnose, it's basically a process of elimination.

This may help-

How very frustrating for you and Lycan.
You have tried extremely hard to find a cause and solution to help him, I take my hat off to you for how much you have tried to help him. I sincerely hope you can both enjoy some quality time, however long that may be for. xxx

I echo Elaine's post - your detective skills have been impressive.

Lycan709

Well, the NeuroVet checked him for Toxoplasmosis, and said that there were no signs. I have no idea any more. His spasms have returned. His eyesight is fine, as far as I can tell. Thank you for your input.
