I'm sure I'll get downvoted but I agree that cats being outdoors is a problem. Not only do they kill birds constantly, fucking up the ecosystem, they shit places and it smells awful, plus clearly many of them breed and that contributes to terrible suffering. Then things like this can happen. Cats can mostly take care of themselves but that's no excuse.

Yesterday I was walking my dog who was doing nothing but sniffing and peeing like a dog would, when a cat jumps out of the bushes, scratching him, hissing, and growling evilly. My dog did not react aggressively. He's 20% pit bull genetically so I'm sure this community would side against him automatically but he literally just kinda freaked out and jumped to his left to escape the attack. I tried scaring the cat off just to communicate that wasn't okay but the damn thing hissed instead of backing off an inch. Then it proceeded to follow us in a stalking manner. The only thing stopping the cat from killing my dog appeared to be ability.

Tldr; you're right, two things can be true at once.
