I really do wish Whimzees would last as long for my dog as they can for hamsters,but unfortunately 15 pounds of muscle and the jaws of a pitbull destroy Whimzees
As others have said it would be far too risky to justify reusing a chew between several hamsters.Not only could it spread illness potentially,but the scent of another hamster within a hamster's habitat could be extremely stressful.
