I've got that toy called Cy-Purr Mouse and wholy annoying! IT's alright at first, but in the middle of the night you would hear "uh-oh! hee hee hee" and we would groan and argue over who left it on.
I have a Cy-purr Mouse too, and I think I have only turned it on twice. I find it too loud, and the cats aren't all that interested in it, so it sits on the floor collecting dust
A toy swap sounds neat!!! Unfortunally I use pipe cleaner toys, I make myself, celophane (sp?)balls, and balls that rattle. I have a toy that I bought at the dollar store that hooks to the bottom of the door, they like that too.
Reminds me of parents after Christmas is over and the toys are all around the house some activated, some not! LOL But the cats who belong to all who gather here aren't spoiled are they? I don't think so!
