I bought one of these for ChiChi our Teacup Chihuahua.As an adult now,she only goes four pounds,and she enjoys light weight toys and Cat toys to play with.The baby keys are great.She loves to carry them and shake them around.It has worked well as a toy because she is not rough or a chewer.I have noticed that some of the Rabbits at the shelter also have them to play with.
A good toy for small pets.

Pros: low cost durable light weight amusement for dog

Cons: None!

My rabbits never get tired of their keys. They have had them for four years now and still play with them on a regular basis. They're durable too - they've had the same set for all that time.

Pros: So much fun

Cons: none

Inexpensive and fun for bunnies. They love to toss them and swing them around.

Pros: Haven't met a bunny who doesn't like to toss keys

Cons: None
