When my previous cat, Rom, was young, we bought him beds and one of the condominium type boxes. He mostly ignored the beds, although he did choose a favorite box of the condominium to sleep in at times. Mostly he chose to sleep on our bed, sofa, bar stools or a chair. He would sometimes nap in a sunbeam at a window or at the back patio door. The cat beds went ignored.
As he grew older it became increasingly difficult for him to reach his favorite condominium box, the bar stools and eventually even the bed or chairs without assistance. He developed arthritis that limited his jumping. He'd stand and look at where he wanted to be, and if we noticed we'd lift him. We then got him a new two story box with the lower box being at floor level and a new round bed with a removable washable cover. He welcomed them and used both. For his arthritis we also got one of the kitty warming pads made to go under the cover of his bed. He spent more and more time in his new warm bed.
Our new cat, Kiwi, inherited the two story box, the bed and the kitty warming pad. Shortly after we got her from the humane shelter, she developed an upper respiratory infection for a few days. During that time she didn't feel well and slept a lot. She chose the bed with the warming pad. After she got better she didn't spend much time in the bed, but used the sofa, or bar stools for sleeping. When we had her spayed, while she was convalescing, she again used the warm bed extensively. As she got better she used the bed less and less until now she only uses it occasionally on cool mornings for a short nap.
