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.
