My cats love my Costco trips. When we get our stuff unloaded I throw the boxes on the floor and time how long it takes for one of them to crawl in. Usually less than 30 seconds.

No toy you can buy a cat is better received than a plain old box. Paper grocery bags are up there, too.

We set up a cornhole game in the backyard. Cat immediately saunters over, sniffs around, and crawls through the hole into one of the boards.

Play commences ... bag slams onto the board containing the cat. Cat explodes out of the hole as if rocket-propelled!

ROFL!

Now and then when we get a larger box like a new printer, I will cut "hatches" in it and ports to make a fort. One cat will "defend" from inside while the other attacks.

Great fun.

Our indoor cats only have an 1800sq ft house to roam in, though my wife is foster caring three kittens in the guest bathroom so it is off limits.

I was doing some work at the NC Zoo the other day and had some rather large boxes left over. They are saving them for the lions. They said they do the exact same thing. :^)
