Mr Snugs KatDen Outdoor Cat Kennel/Shelter - Granite (Various Options) - Kennel, Door & Liner/Mattress Combo

Tough and waterproof, easy to clean. Foresee it lasting a long time, but rather small space inside. Thought my cat would not use it due to size, but she has and does! She shelters happily in there from rain and if out late. If it was more spacious - it would get five stars.
