I gave mine to the rescue centre. It was sat on once, when I bribed him with treats. Also play tunnel ( rushed through once when bribed with treats) Also, come to think of it, igloo bed And cardboard scratchers And luxury cat bed And assorted, extortionately priced, wet foods And many and varied cat treats..
I certainly would have done when I got my first cat. It would have saved my spending £££ on a new one which she was not remotely interested in . Having had this experience, I'd recommend any cat-servant tested the water as cheaply as possible with cat trees - if it floats your cat's boat, you can always buy another new one for your cat to then ignore in favour of the old one
