You can combine many boxes into an elaborate cat castle. I am so sorry for sharing this. Cut holes in between the box-floors and build cardboard ramps with scraps. Again, I apologize. More scraps can be used for fortress walls along the top. You can build wonderful, elaborate monstrosities this way. Beware this dark magic, it may consume you and those cats around you. BEWARE.

Edit: Employ the handyman's secret weapon, duct tape, liberally to make a good bond between levels. Masking tape works in a pinch. Your kids might even help decorate with marker and/or construction paper. These are the darkest of arts, tread carefully through these waters.

I had a spindrift box from Costco for 2 months because my kittens chose this box to survive.

It was their space ship until an unfortunate roomba incident …

My dog loves if I put snacks inside Amazon boxes or toilet paper rolls, or any cardboard really. Treats inside and close it up. Poodle dog takes it into her spot and 10 minutes of tearing up the box to get to treats. ❤️
