Once I left my house for a week, and I forgot to feed my cats, because when I got back the biggest one, Chewie, had killed and eaten the other two. Is this normal for cats? Cus if I leave my house again for a week and forget to feed my cats again, I don't want Chewie eating my new 3 cats, Ingus, Wingus and Bingus. I don't think I'd be able to handle such a heart ache. And I love Chewie too much to give him away or put him down. WHAT SHOULD I DO??
