I was so impressed with these cat caves when I took them out of their bags. They are the thickest caves I’ve seen and generously sized. I kept my fingers crossed that Naz and Nino would like them, because you know how it goes, these purchases are often more appealing to the cat owner than to the cat, who prefers the box. Not this time! As soon as my boys saw them they started investigating, and soon after took up residence. I wish I could add their pictures here. Just adorable! My ginger boy in the orange cave, and my gray tabby in the purple. Perfect!
