Oh no, poor Jocky boy. I sure hope the meds do their thing this time and he gets better.

And....I'm just a kitty owner like you and am not a vet by any means.....but....when they say if he has started eating by Friday you can bring him home....well...don't you think he should be eating way before Friday? I mean, they said this on a Monday.....sorry to keep questioning your vet, but....

The good news is he "pee'd for Scotland" (I love the way you put that ) and that can only be a good sign.

Please keep us updated on his progress. I feel so sorry for him that he has to stay at the vet all week, but I guess that's the best place to be when you're not feeling well.
