My kitties love these mylar balls, in the jumbo and smaller size. They are inexpensive and you can find them at any pet store and some other stores. I found a 4-pack of the smaller ones for $1 at the grocery store today! They do make some noise so they can be annoying during the night if that is the toy they choose play with at the time! I frequently have to gather them out from underneath furniture, but that's with most toys...

Pros: Fun and inexpensive

Cons: makes some noise, get lost under furniture!

My cat comes running when I crinkle this. Maybe it sounds like mice scratching to her, I don't know as she's never seen a mouse. This goes through the laundry well. Why do all cat toys end up going through the washing machine?

Pros: Crinkly noise rousts cats out of sleep.

Cons: none

My cats love these things. They carry them around and like to wrestle with them. They seem to like the noise they make. The larger size is nice because they don't get lost under the furniture as easily as some other toys.

Pros: low choke risk for cats--very entertaining

Cons: none

My cat is entertained by these for a while, and they aren't quite as loud and annoying as the plastic balls with bells in them.
I buy several at a time, and when we move furniture to clean, they all seem to be there.

Pros: Not as annoying as the cage balls with bell in them

Cons: Still not totally silent

The texture, bounce, and size of these balls is a big 'yes' for my kitten.. Make sure you buy a couple of these, since they tend to get lost around the home easily.. Overall, a good, cheap buy..

Pros: Fun for kitty, cheap for purchase..

Cons: Hard to keep an eye on..
