@margo,
Thanku everyone - he's doing well today. He escaped out the door this morning for about 10 mins but came back in without too much cajoling - a few whistles and the hint of sardine aroma (peuw) has wonderful effect on the kitties

He's had his antibiotics - took them no probs thankfully and metacam anti-inflams and pain meds dropped onto the sardines - and munched it all straight down. Phew.
So, so pleased he is doing well - thanku for your wishes for him - even tho it looks nasty, I'm hoping/fairly sure he's not in pain. Just so grateful I found him in the house and could get him straight to the vet - he was verra brave. The vet is an opthamology specialist that folk come near and far for his expertise in the West Country - so that was very fortunate.
So, all is well with the black boy - now, if I could only get him to stop scrapping with his brother - it really is playful scrapping and tumbling, racing like twisters through the house - he's less likely to scrap outside - but he won't be used to being the one eyed black shadow - so..... will see what vet says on Saturday. Think he may be able to go out again once he's had his first post op check.
I need to think about insurance for the cats.... the cost of the op (not that it isn't worth it - he's worth every penny) was the cost of a holiday to Italy or feeding a small nation for a year. Hefty vet fees - not sure I can do that again tho gawd forbid any of the animals/family get hurt - so, gonna have to find out about insurance. Always had the animals insured in my previous life with a regular income - but, you know..... times a change. Need to make some phonecalls. One of those responsible jobs I keep putting off.
Kitty is doing well right now - so that's good news.
