    I've used Ideal products many times. Good quality and ease of installation. I've got eight cats. The biggest, Kona Kona saw the "ChubbyCat descriptor and was offended! I changed his name to Snowflake.

  3. So far so good 4 Star Review

    Recently built an enclosed cat patio for my 4 year old Russian Blue. I live on a busy street so allowing him to be an outside cat wasn't an option for me. I utilized the cat door by placing into a piece of plywood that was fitted perfectly for my bedroom window and allows unlimited access to and from his patio area. He needed a little encouragement at first to understand how the door works, but he's a pro now. He's a decently large cat, not fat by any means, and the large cat door is perfect for him. He's about 12lbs and 13in from floor to shoulders. Like my headline says, so far, so good!
