whats the answer then? how can one redeem themselves of such sin?
I just gave you the answer before you asked another question.
Idk and idc. If someone has already done something like that then I don't believe they should have another pet. They were already irresponsible for the first, why chance ruining another? It's a living creature, not a toy that you toss away when you're bored with it or when it becomes inconvenient.
