Cats love it but require supervision!
I tend to leave all the toys of this set out for my cats to play with, apart from the feather ones. They especially love the big mice. However, one of my cats managed to chew off and swallow the tail of one of the mice recently! Had a few stressful days waiting for the tail to show up in the litter box (which it did!) but would advise other buyers to have the mice as a supervised play toy only.
