My cat can be incredibly specific about what he likes to lay on and sleep in. After going through aat least aa dozen cat beds/caves, I've found something he uses consistently.

I have one cat that loves to "perch" and she loves the top; my other cats loves tunnels and hideaways and he loves the inside to play and hide.

I had just unboxed the cave and my cat being the nosiest little thing was alread tring to see thaw was in the plastic bag.
