My cat would look at this and laugh. But I did see a video somewhere of a cat who actually used one like this but only when it was being watched.
I’ve seen a bunch of videos of cats voluntarily using them. Also one of how to get your cat to use them by using food as a reward.
None of my cats will use this, what with them being plushies and all.
Dogs > cats.
Catshirts > dogshirts.

As a fellow cat person, I know some of the cat peeps at least, I see them tagging each other on cat shirts or posting pics of cats.
A hamster wheel for cats. Who knew!

Maybe Woot! should adopt working cats for their servers instead of hamsters.

But will you use it?
So…
Yes?
Egad…how many cats does this person have?
