This bed is larger than most other cat beds, making it PERFECT for cats and/or small dogs. My cat isn't usually a fan of smaller beds and prefers dog beds, but jumped in this one before I finished putting it in the right place! It's roomy, very well made, and attractive in my living room. I love that it has higher sides but then a lower entry to help him get in and out with ease. In the week we've had it, it's become his go-to bed, we will be purchasing more, thank you for a great product! I was looking for a replacement pet bed for my elderly cat. His original bed was a dog bed I had purchased at another store however after years of use it had gotten into a really disgusting state. It was large and cumbersome and unwashable, But it had firm sides that he could recline against if he wanted to. Finally that old pet bed needed to be thrown away because it was basically destroyed and so I started searching for something that could be machine washed if it got dirty and my search led me to this bed. It came in a very small compact box But as soon as I unwrapped it the bed started increasing in size due to the foam being allowed to expand as designed. I was impressed with how it started to take shape. Within five minutes of putting the pet bed in the spot of the old, beloved bed, my elderly cat jumped in it, as shown by the photos. He shuffled around, made some circles, and settled right down in it to groom himself and that’s where he remains. I know the manufacturers instructions say it takes 24 hours to fully formed into its proper shape but I don’t mind and neither does the cat. He’s quite happy with it the second I put it down in front of the fireplace. I will update the review to see how long he sleeps in it but I suspect he will enjoy several hours of naps. This cat bed is awesome. Its bigger than I thought it would be and the quality is better than expected as well. The packaging is weird because it's vacuum sealed or something in this little box and you have to cut it out of the packaging and then it expands. It's really cool. My cat hasn't had much chance to use it because my dog stole it from her, but either way, I'd call it a win! She “Liv” didn’t like it at first till I threw her blanket in there. Maybe because she thought “what is this?” I don’t know lol. But this is a wonderful bed for cats!!! It has PLENTY of room and is super comfortable!! Love how it keeps her warm and plus it doesn’t look cheap at all! Absolutely a must for your cat!! I love how the cat bed has an interchangeable cushion, which my cat liked a lot. She kept coming in and out of the bed, exploring and seeing if it was hers. The beds soft and warm and my cat kept playing and walking in and out of the bed in less than 24 hrs of getting it. So I’d say I’ll be seeing more of this bed, and hopefully my cat continues to enjoy it :) For people looking to buy, the bed is bigger than it looks when you open the box it’s packaged in. And my cat enjoys it! I do not have a cat but I do have a small dog. It took a little while once opened to fluff up, but once it did I was surprised by how big it is. The inside flips so there is a summer side and a winter wide. My dog greatly likes the bed. He has been using that over all of his other beds in the house. Overall, a great product! We have an outdoor cat, and he really loves this. He is nice and snuggly on cold days and prefers to lay on a separate towel on warmer days. So, the self-warming technology must really work! The short fabric is soft, but doesn't catch lots of muck even though it's outside.Our only complaint is that this was larger than we really wanted, but we could not find a comparable product in a smaller size. He did not immediately take a liking to it, but once I put his blanket in there, he's gotten in and almost never gets out. He LOVES this bed, and it keeps him nice and warm. I have purchased two other beds in the last month on a search for something he would fit into comfortably and would like. Neither gave him enough space until I found this bed. It's very well made and he finds it very comfortable.
