Well, I had to get one of these a long time ago for the rabbits and guinea pig. They really like them and have a great time playing with them and chewing them up.

The only bad thing is when you are laying down on the floor and the rabbit decides you need to play also and he flings it into your face! OUCH!

Anything for the animals tho.... I'll heal.

Pros: Really popular

Cons: having it flung into your face

the rattys love this toy they now have learned(at least I think they have) that there is a large walnut inside whe they get to the center of thsi ball. Very entertaining...

Pros: when they have chewed long and hard enough surprise

Cons: .........

I dont like the nut in the middle, and will take the little sticks out and remove it so my rabbits dont get it because they can not have nuts. Other then that they love it, it doesnt last very long in my house and they get it disasembled in no time,lol.

Pros: it is great

Cons: the nut in the middle

I'm not sure what my rabbits did before they got their nut knot nibbler. They spend more time with this than any other toy.

Pros: great fun

Cons: none

Snickers loves nibbling on his Knot Nibbler. Not only does it serve the purpose of keeping his teeth in check, but it also serves as entertainment for him. If you have a piggy, this one is a must.

Pros: Colorful, keeps teeth in good condition.

Cons: None.
