Description: A while back, I saw a photo of an old bookshelf converted into sleeping compartments for cats at a cat rescue. It was old and dirty, but I thought it was brilliant. Sooo- I had the idea to buy a 4×2 Ikea Expedit bookshelf to convert into an entire Cat Activity Center. The beds, toys and scratchers are held to the shelves with industrial strength velcro so I can replace individual items as they wear out.
The carpet and sisal are attached with staples. I had two extra spaces when I was done, so I added some regular rope for them to play with and some self-grooming brushes. As you can see, the center is a hit with my cats (I volunteer as a foster for a cat rescue).
The best part, I got the Expedit second-hand from a neighbor, so the whole thing was MUCH cheaper than those cat trees you buy at the pet store.
