Did I raise my son wrong? Child support for cats should exist

So as this title says, yes I do have a son, I catnapped him making him blood related.. he was always an outside cat (a stray) I'll only feed him (and others) but as of a few days ago he brought back triplets nd is now disowning one of his sons (his son is old enough to be off his mother) so I catnapped my childs son and now my grandchild is beating on me
