I am very underwhelmed with this toy, and I think my cat was as well. I purchased it when I was going to be away for a couple of days, thinking that this was a toy that my cat, Mike, could play with on his own (as opposed to requiring human interaction). Also, the toy is very cute--not a realistic looking mouse, but more a cartoon version of a mouse. I attached it securely to a door knob and hoped for the best. My cat preceded to ignore the bouncy mouse toy while it hung on the door. Finally, I attempted to engage him with the toy by dangling it over him when he was in a playful mood. Eventually he batted at it half-heartedly but never seemed totally sold on the toy. Once I finally got him to play with it, the string abruptly snapped on the toy. This toy does not seem to be of very high quality. I trimmed the broken string, so the mouse could still be used to bat around the floor, but my cat continues to ignore the mouse most of the time. I wish I had saved my money!
