Also today I showed him a mirror and said “Look Gregory it’s another Gregory! He’s gonna eat your food!” and he “punched” the mirror with his paw lmao.

Why would someone get a cat high on meth?

If he was an indoor cat acting this way, I'd say he may be sick or injured. I would continue to feed him and put out clean water for him, and if possible I'd try to get him into a cat carrier and bring him in to the vet. In fact, better yet, if there's one you trust then you can ask them for advice on what to do.

Also, homie, c'mon. You are not scaring the cat away with your interest in them. You feed them tuna and care about them. For a cat, that is much more than enough. Ol Greg is just a little sick or hurt and is keeping to himself for that reason. I'm sure that when he goes back to normal, he will love to play catnip glove with you again

Some cats clutch to you immediately, some take years to have a favorite human. Constant positive interaction is the way. Try to play with him after feeding him but don't be pushy.

If you can give him a permanent indoor home, that would be the best for the cat longevity.

But in any case, some cats are assholes who would butthead and mew mew you one second and bite you right after, can confirm. Some cats are like that.

Also what kind of imbecile drugs a cat

Hello, maybe he has troubles with humans since he was left behind, and he fears being left behind again. Imagine you have people that care for you and suddenly be left behind without notices, must be horrible. Thank you for being kind with him, poor thing

Maybe he’s just horny?

I’ve had a problem my entire life, with going too far when I really like someone. It always results in them not wanting to be around me. Gregory isn’t a domestic cat anymore—he does his own thing, and I’ll sort of like, follow him around trying to get him to eat his fucking food. And the reason he’s never done this before is because I’ve only recently started obsessing over him.

Kinda sounds like you know what the problem is, cats are very independent creatures, and like some people, they can be overwhelmed easily, especially considering you are many times larger than them

Also just in case I hope that was fresh tuna not tinned because they can't handle the level of salt in human food

Idk anything about why cats do what they do, but he's really cute.

I'd say you're winning already with the cat coming up to you relatively close when getting food. My cats have a variety of personalities and quirks that just took a while to figure out. The one does not like to be touched or picked up unless she's on one of her perches and even then you get like 5 strokes before she starts side eyeing you and getting ready to walk off. I've found that I tend to have decent success with them when I let them dictate the interactions and as I learn more of their cues I can pick up on when they're done.

Chasing them after they start running will usually just piss them off and make them more defensive since they're more alarmed you're going to hurt them. Ended up having a long road to repairing my relationship with the one after I had to chase her down and corner her because she needed to be bathed which made her avoid me for months after and she's learned every trick I've used to trap her.

Start out letting him sniff your finger and judge from there how he's doing, it's more just a greeting and if he's not having it he'll ignore it.
