Fun, but don't leave them out when you retire for the night. I have a very nocturnal female that loved these and always seemed to drag them out around 2:00 a.m. Fun, but I don't see the purpose of them glowing in the dark. Like she knows!

Pros: keeps you up at night

Cons: none

Cats love to chase these glowing balls and they love the sound of the bells too.

Pros: Cats delight

Cons: None

these bounce pretty well and it's fun to watch kitty chase around

Pros: fun toy!!!

Cons: none

Cats do like to bat and chase balls. What is good about these glow in the dark balls is that since they glow in the dark, they are safer for humans who get up in the dark for any reason. The balls can then been seen and not stepped on.

Pros: Fun for cats

Cons: none

My husband bought these as a little gift for our cats, figuring they would like the jingly sound and the lights. They were all very much interested at first. After a bit, the older/more sleepy-natured cats got bored and ignored the toys. But the younger cats and the more playful cats loved these and kept right on playing with them, just so fascinated and excited.
I think alot of cats would like these glow-ball toys :)

Pros: Alot of fun, especially for our younger cats

Cons: no cons
