To keep your cat happy, you might buy toys and massive cat scratching posts. However, if you truly love your cat, you’ll go all out and do what Chris Poole did to help his two cats named Cole and Marmalade, celebrate International Cat Day. Chris built them a maze built out of 50 cardboard boxes.

Now the cats can run through the maze and chase each other while looking for treats. Since cats love cardboard boxes anyway, you might as well buy card box boxes instead of expensive cat toys and let them play with the boxes instead.
