Or maybe they’re trying to find some humor in a pricy vet bill.

JFC get over yourself. If the animal does it to itself, and you rush it to the vet like this person did, that is in no way, shape, or form ‘animal abuse’.

I love from-the-hip judgements like this. Absolute (and completely unfounded) confidence in something you don't know. Glorious.

In the future, you can throw the image URL into a service like TinEye and get results like this. If you sort by oldest you can usually find some context.

If you look closely, you see it's at the vet. So the cat likely isn't placed in the collar by the owner's intention.

Is it abuse if they do it to themselves?

everyone knows the sign of a responsible pet owner is keeping it locked in a cage 24/7 so it can't hurt itself
