Cat 1 - being picked up. Usually makes him very squirmy.
Cat 2 - being petted when she didn’t initiate affection.
Cat 3 - interacting with cat 1, she doesn’t like him, especially not in close proximity, which he hasn’t picked up on despite her hissing and smacking him regularly for the last seven years
Cat 1’s inability to understand boundaries with cat 3. He (cat 1) gets along great with cat 2, and he thinks cat 3 is also his best friend, but cat 3? She hates him (he doesn’t respect her boundaries). And he tries to play with her in the middle of the night which means we get woken up by hissing and yelling and whatnot.
I love cat 1, don’t get me wrong. But he’s like a big dumb puppy in the shape of a cat.
