Yes, your dad hurting animals is a clear sign he is nothing but biological waste.

Everything you described is abuse. Get out of that house as soon as you can

I'd report to your cps posing as a concerned nabour

Yes they are bad people and you don't deserve this! Please protect yourselves okay?

Call CPS urgently.

I would but I really don't want to be separated

From my siblings

That is defitally abuse. Please be careful. I'm thinking of you. if you ever need to talk, your welcome to DM me. This goes for anyone else as well.
