I have a 1.5 year old Burmese male cat and a 9 month old Burmese male kitten. They were the best of buds as of Sunday. I took the little one to the vet on Monday morning, had him neutered and front declawed, and picked him up today. The older cat now acts like he has never seen the little one before and is basically hostile. What gives? And yes, I checked to make sure they gave the right kitten back...
