What I love best is the quality of the stitching and the durable zipper. It's so easy to zip open and closed. Cats love being able to crawl inside to the warmth of the heated pad. They also enjoy having sunlight warm them from the above clear dome.

First we bought a k&h heat mat for our sick, elderly kitty, then his sister kept stealing his new warm spot. Then, we got a larger heat mat, but his other brother kept stealing that spot. Now, we have the space pod, and finally all three cats can be warm and cozy any time they please. The kitty who loves the pod the most is ~7lbs and fits very comfortably. I don’t think she and her brother (10lbs) would fit together as happily without two doors, but he also fits inside easily if she’s not there.

All of the cats tried this out, including the 15 lb heavyweight, who could not completely fit inside it. All the better for our smallest and oldest cat (14 years, 7 lbs) who has plenty of room to fit, keep warm, and observe all the other cats - she owns the new space pod cat bed now!
