Here are a few ideas when using the shredders. First off I've woven one into a sea grass mat, this will be hung in a cage for a pet bird but would be ideal for a rabbit or guinea pig too. 

I've used some pieces on a chew toy which i just cut to size and hole punched. I've also used it on my gerbils play stand in their tank. It's gone down really well and i can say its real value for money.
