Barney and Cowboy have a strict routine of eating together, then pooping, then napping. Barney usually naps on the cat tree or hammock. Cowboy might crawl into your lap and become a purr machine, or he might go into his super secret hiding place which I havent found yet. After their nap its Wrestlemania time! Zoomies and tackles and chasing balls and bothering the big cats. Repeat routine. Theyd love to go together but I think they could go separately to homes with other active and playful kitties. Or maybe even playful small dogs. They dont mind my big dogs at all. Use them as trampolines.
