My half sister is abusing the family cat.

My half sister got a kitten a few months ago, and she is treating it like a toy.

She holds the cat when its trying to leave, pulls it by its tail while its trying to hide from her, throws it around, puts her whole bodyweight on it to hold it when it trys to get away, et cetera, et cetera.

The cat is very vocal about its miscontent aswell, but every time i say anything, my parents just tell her to stop. Which she just ignores and continue.

Every time ive intervened, they've gotten mad at me, saying that shes just 6 years old and doesn't know better. If she doesn't know better, i dont think she deserves a cat...

I just cant take the cats screams for help, not being able to do anything about it.

If this continues, i will stop visiting them, and probably report them to animal control aswell...

Hope the cat claws her eyes out or something. Thanks for listening to my rant
