This is the best thing i could've bought for my cats. I have two adult cats and one kitten and they all sleep and play together on this Sport pet cat play center. They are always on it. I love the fact that this brings toys with it cause it interest cats more. My cats are playing with the toys at all times when they are on it. It's easy to assemble and there isn't much needed to build. This cat play center allows you to add extensions so there can be more areas that your cat can sleep and play in and That's my favorite part. I have bought my cats every extension possible and they can't get enough of it, My dog sleeps on the bottom of the jungle gym also which i think is funny. I love that i can have something for my cats to enjoy. This is a great gift to give with someone with cats and this is also great to get for your own cats. You will never see it not used. You will love seeing your cats enjoy this jungle gym and your cats will love playing with it. Its also great in price. Not expensive at all!!
