I did, too. Got some free labor as a gift. Just a high shelf or two that they can get to (carpeted or padded, if possible) adds a lot. Mine absolutely love it.

I am surprised by how much my cats take to it. Start with just a shelf or two and see what they think...

If homes are traditional, cats will catify as they see fit....keep curio cabinets SMALL because each cubby hole big enough for a cat to curl up in will have the display items knocked over or knocked out

Jackson Galaxy jerks cat lovers around a bit ....no cat is from an alleged hell....calling cats aggressive is wrong when cats are DEFENSIVE in difficult situations

@GreenAtheist The show makes me uncomfortable at times as often the problem is a cat-clueless human or two... My cats definitely had already made use of potential perches present in the house. Adding these (a gift from family) just expands those options. The cat gang started exploring within five minutes of installing. Guess they like it!

Jackson Galaxy never "cures" the cat, he fixes the stupid owners, lol. It's amazing what having a place to get up high does for a cat's personality.
