When we first got Squeekers back in May she was TERRIFIED of it! I guess her previous owners didn't vacuum their house much or something. After a few months she got used to the sounds though. Now she just hops up onto her cat tree and lays there with her ears back until we're finished with it.

My RB cat Perkins however LOVED it! We used to vacuum him to remove excess fur and he couldn't get enough of it! LOL! They're all different.

Misty doesn't like it at all, but is getting better about it.
