It's been 2 weeks since he was neutered. He LOVES having attention when I go into the room to feed him and sit with him. The only blood drawn was with his claws, not his teeth. He's been an inside kitty for about 3 weeks. The vet says he's about 2 years old and in perfect health. He has the eyes and shape head of part siamese/oriental and is VERY verbal. The vet said it would take about 2 weeks post neutering before all the testosterone is out of his system. I tried putting him in a carrier and letting my cats come up to it to see what happens. He hisses and spits profusely! I'm going to give it more time and see what happens. My main concern is for my cats safety.
