Thanks I do appreciate all your input. Our vet isn't very pushy at all, she actually thought it wasn't a good idea measuring all the pros and cons. KC's blindness came on slowly too. We also noticed her drinking a lot of water and eating a lot and not gaining weight.
Funny, we can't move anything in the house either because KC is so accustom to things being in the same place. I have to tap my foot to let her know where to go sometimes but for the most part she is fine. She's a wonderful little girl and so loving. Not sure who said it but you are right, age will win!! Turbo just keeps going back for more lol!!
Oh and sorry, yes cataract surgery.
