Thanks guys, quick update:
Well, yesterday Wally's eye was looking so bad we thought he'd definitely lose it, which would be awful for him because it's his good eye but today it's looking slightly better ( in so much as it can, it really does look worryingly gruesome ) so we're cautiously optimistic for the moment.
Yoshi is still showing no interest in food, he just wants to sleep, he's also losing loads of hair ( although he still looks very fluffy ), he's always been quite moulty but I could knit a jumper with the amount of fur that's coming off him at the mo. I've been giving him Critical Care at regular intervals but even that's a battle because he really doesn't want anything and just wants to be left alone. Having said that he doesn't like being picked up and faffed with at the best of times, would rather be fussed in his house.
To look at him he still looks bright eyed and bushy tailed, his coat's shiny and when he wants to move he's moving around fine but he's got a wet tummy from lying in his own wee and poo which he's done a few more of so that's a bit of a relief (I gave him a gentle sponge bath yesterday, that was not appreciated).
He also has a permanently wet chin ( which is why Vicki has added looking at his teeth to the friday list of things to do when he's under, she couldn't see anything wrong with them on Thursday though and got a fairly good look at left and right molars). The lump under his chin seems very hard ( I'm wondering if it's affecting his swallowing which would explain him not wanting to eat ) so I'll be taking him in to the vets tomorrow with Wally rather than wait for his friday appt. but this means he won't be seeing Vicki, his regular vet.
They're both on antibiotics and Pro C probiotic and Wally's on metacam and Tiacil eye drops too.
