of my cats was food motivated and the other took to it right away after getting out the laser pointer.
after the first day two of my cats would use it with out encouragement and the rest started using it without help after two days.
i love the cat wheel and have every intention of getting another since my cats have started not wanting to share it.
my only complaint would be that the outside of the wheel does not look the best but i understand it's functional and keeps the weight down.
