Kitchen carts designed to hold microwaves or other appliances are usually sturdy pieces of furniture. Consider using a multiple shelf unit like this one, highly rated for its intended use, as a piece of furniture for your cat! There are several different space-saving ways you can use this free-standing baker's rack cart for your cat.
Use idea: Litter box station with storage
Keep your appropriately-sized litter box on the bottom shelf of this unit and use the other shelves for storage of litter box supplies like bags, extra litter, scoop, liner, and more. The shelf above the box will act like a hood to prevent extra scattering of litter as kitty exits the box. You can DIY a curtain or other barrier around three sides of the box, easy to hang from the shelf above, to prevent even more litter from scattering.
Use idea: Cat feeding station with storage
Feed kitty on one of the shelves of this unit. Let your cat free-feed by placing her food on an upper shelf, away from other pets. Store dry food and cans, extra dishes, and other cat supplies on the other shelves.
Use idea: Multiple level cat tree
Simply add cushions, blankets, or pillows to the different shelves to turn this rack into a multiple-level snooze zone for your cat! Hang toys from the top shelf for fun. Add scratch zones by attaching sisal rope or cardboard to the legs of the cart.
