It never fails. You buy your cat a really snazzy (and probably expensive) cat toy, and all she wants is the paper bag it came in.
As you will see from this video, this romantic yen for paper bags is inborn in cats. Little kittens have it. I’ll bet if you rattled a paper bag near a pregnant cat, the babies in her womb would get rowdy. “Oh, we just can’t wait to be born! A world filled with paper bags awaits us!”
