Like many cat owners, Andres Acosta tries to keep his cats happy. For Christmas, he bought them a $40 pet house online, but “they ended up sniffing it and never looked at it again.”

That’s when Andres saw the empty boxes of gifts stacked around his house and got the brainstorm to turn those boxes into cat toys. Not surprisingly, the cats love the boxes while ignoring the more expensive pet house.

So if you want to keep your cat and your wallet happy, forget about expensive toys. Cardboard boxes are far more interesting to cats and cheaper too.
