Birds are incredibly smart, and a challenging foraging toy can provide hours of stimulation.  Shred Master™ gives a roll of shredding action in an incredibly strong plastic container.  It is actually made from materials used to manufacture bullet proof glass. That is why we say it is Bird Proof™!  Birds simply pull paper off the roll and shred away.  Have not heard of any using the paper to write notes, but birds are smart!  The small is 2.5 inches wide, while the large is an impressive 4 inches.  Colors vary.

Refills available.
