How old is Max? Casper was done when he was almost 6 months, and Kitty when she was 8 months old. We didn't give any painkillers, just few pills from the vet agains infections. Casper was groggy for a day, then he was back to his normal self. Kitty on the other hand, was feeling blue for couple of days, and I think it took a whole week before she was back to herself! She did do her normal stuff, play, run etc. but was a bit slow, and tired of course! I can't believe the price! $500??? WOW!!! Now that's alot! For Casper the operation was $39 and for Kitty $71
