I bought the 3 Tier wall maze (with the scratching pole) and my cats are obsessed. They took to it right away, exploring, wrestling and finding their favorite perch spots.
Instructions feel a little complicated at first, but once you get the hang of it, it's a solid and well-made set of shelves and pathways. I had a question about a piece of hardware that was provided at the customer service team was prompt in their response and super helpful.
If I had more wall space, I'd buy more products from Catastrophic!
