Oh, this is heckin' cool. Any cat would be interested in their own Whack-A-Mole!
And the best part? It's inexpensive and looks pretty darn simple to create it! If you do go ahead and make this awesome DIY, just be realistic and not hold any attachments to it, we all know cats can tear up and destroy pretty much anything!
Happy Whack-A-Mole-ing!
