Step one: let him hide or shy away from you if he wants to. He wouldn’t let me touch him for a couple days after we got back from the shelter. His comfort was more important than me getting to touch him.
Step two: make yourself nonthreatening. In my case this meant being very quiet, bringing food and lying down on the ground within his eyesight as an invitation to investigate.
Step three: watch his body language and don’t do things that make him uncomfortable. Turns out my cat often bit when he was overstimulated so I made sure not to overwhelm him.
Step four: draw lines, but not with brute force. Even though his biting wasn’t meant to hurt, I wanted to make sure he wouldn’t injure anyone in the future. So I decided when he bit me, I’d yelp “ow!” And then withdraw all physical contact for a few minutes, sometimes leaving the room. Now he never bites, but sometimes he puts his teeth on my hand and then thinks better of it.
Step five: provide a good outlet for destructive behaviors. Aka PLAY WITH HIM, SEVERAL TIMES A DAY.
Step six: be patient.
Step seven: get lucky and somehow pick up the best cat in the entire shelter. I don’t know how it happened but he’s a godsend. He’s literally cuddled me out of a panic attack. We both really needed each other.
this is basically it??? for any animal. and human. both of you get to set boundaries for what you’re comfortable with, both of you respect those boundaries, and the goal is not ‘oh i get to pet the kitty’ or ‘oh i made the parrot talk’ but ‘we have a good solid relationship where we understand each other and are both happy’???
