I’m a 2yr old tom cat, a domestic shorthair if you must know, and I rejected this den as too small and too sweaty. I didn’t even go in as if I had, I’d probably have had difficulty getting out as it rolls around. My person also folded it into a cradle for me, but it was still too hot, all that synthetic fluff. Why would I bother spending most of my waking hours keeping myself clean and handsome only to sweat in a sauna? Give it to a kitten. Bleurgh.
