The best investment I've made for my cats and my cat sitting business. The base got broken in transport. Call the company and a new base is in the mail. Sturdy construction, big enough for normal size cats, obese cats will have a problem. It took me less than 30 mins. to assemble, easy I'm 64 yr old woman. Now it is waiting for the base. My cats have ben in and out and I will be purchasing another . Great playpen for outdoors it has wheels. I will add a picture once it is together
