Great for outdoor cats in the summer
Color: Gray, Size: 18"x24"
I bought this for my outdoor cats specifically for the summer since it’s get really hot. I always see them relaxing on this and they seem to love it. It’s easy to wash and is quite soft. It’s also quite thick and of good quality.

Nice bed
Color: Blue, Size: Large (Pack of 1)
Good quality dog bed. My pittie loves to burrow himself under blankets so I figured we would give this a try. He hasn’t figured it out yet but it’s his new favorite spot to take a nap when he’s not on our lap. Love the color and seems to be nicely made. I do wish it came in a bigger size but it’s still big enough for him.

Nice quality bed
Color: Blue, Size: Large (Pack of 1)
Nice quality. My dog loves laying on this bed but hasn’t yet figured out getting inside. I cover him after he lays and he seems to enjoy it

Cozy Bed, Just Needs Fluffing
Color: Blue, Size: Large (Pack of 1)
Our dog took to this bed pretty quickly and seems to like curling up under the cave cover. It’s soft, roomy, and gives that little tucked-in feeling a lot of pets seem to love. The cover doesn’t always stay perfectly shaped, so I have to fluff it back up now and then. Other than that, it looks nice in the corner and seems comfortable enough for daily naps. Solid bed overall, especially for the price.

Great for the money
Color: Blue, Size: Large (Pack of 1)
Really beautiful, I'm not sure of what size I got but it is BIG, I have a 50lb Boston terrier and he gets lost in it, very soft with a lots of foam, he loves it
