How long will it take for a Tom to quit being aggressive?
He was a stray, very loving cat, to people, not so with GG. I had him neutered last week.
GG has been spayed, years ago, and she is an indoor cat, Tom is outdoor and probably will remain that way.
GG goes outside to potty, she only uses the litter box in an emergency, such as me being late getting home.
He has always stalked her and attacks, from behind, claws her and bites. He learned better than attacking her face to face, she's bigger and can kick his butt. But she doesn't want to fight if she can get away.
He seems more aggressive now than he was before being fixed! He actually jumped through the door to attack when I let her in earlier! A quick hit and back outside, but right under my feet!
