Thanks Nae, thanks everyone. And yes, Dinah does look well, especially if you consider she has thrown off kennel cough and a severe bout of vomiting, (not to mention a poorly tootsie) in the last couple of weeks.
The garage, now tidy(ish) and cleared of hazards (we hope) has become a great rumpus room for the kittens - scuffle round the floor, sniff for mouses, jump on mum's jeep (right up, on the roof), jump down, there's a rope loop, swing on it, jump on the jeep, jump down, hide behind dad's bike, sniff, etc etc .
