Up at the vet first thing this morning (he's on monthly injections now for his arthritis and was due one, not an emergency or anything!) and vet said he's looking a lot perkier now he's better hydrated, which I agree with, he's certainly more back to his normal self.
We asked to have a look at his last blood test results cos I forgot to ask for a copy at the time, we knew his kidneys were fucked at this point, but seeing the numbers was a bit
It's all about his quality of life, which for now is pretty good, all things considered.
We got a B12 supplement for him as that'll probably help a bit too, cats with late stage kidney disease tend to have it go right through them without much of a chance to absorb it, so a daily supplement helps with condition and energy.
His weight's the same as last time (well a little higher, but last time he was weighed he was very dehydrated, so it's just hydration making the difference) and the vet said don't expect him to gain weight at this stage, just keep him eating as much as possible so he doesn't lose weight too rapidly.
I mean we know he's on his last legs but we're all (vet included) happy with the way he's doing at the moment, given his age and the state of his kidneys which is just one of those things that a lot of elderly cats have trouble with (in the wild they wouldn't live long enough for it to be a factor but common in elderly pet cats of all varieties) - everything else seems to be working OK for now.
