Animal cruelty is denounced in Islam. The Prophet Muhammad (Peace Be Upon Him), held cats in extremely high regard, and spoke specifically against aninal cruelty.

Animal cruelty happens in every culture. As far as why immigrants in western europe are more criminal while in the US (legal) immigrants commit less crime than the native population, that is because here to immigrate you need a reason, in Europe they will basically ship you to their countries because you're brown, and give you welfare to do nothing all day.
