If he wants cute babies then fine, but big mammals tend to live longer than small household pets, so why does he keep making kids with hamsters and shit when he's scared of outliving his children. If a lion or elephant aren't available, at least pick one of those long living birds. A tortoise is even better, some of them would outlive you.
OMG!!! YOKATTA!! we've seen the babies too many times already so it's a very bold move to kill them after all this time.. unless this author is fukin sadist.. which i respect but THE POOR BABIES!!
