I was worried my cats would not like this, but within 10 minutes of putting it up one curled up and took a nap right away. They all love it, I think I will have to buy at least one more for them. One cat (the one in picture) is 15 lbs (not a fat boy) and he fits in perfectly, so It's spacier than it looks. I recommend it! The pillow is good enough, but I put an extra blanket for them as well.
