We went to another cat show today and they had a booth set up called Oxyfresh, they sell liquid that you pet in your pets water and it cleans their teeth %60. They also have toothgel and toothbrushes for pets, shampoo, deodorizer and a bunch of other stuff, they also sell people stuff. Has anyone heard of this and does it work? They are very nicely priced amazingly enough, here is the website: http://www.oxyfreshww.com/pet/default.asp . I really hope it works! If we hear good stuff, or don't hear anything bad then we will buy some at the dog show in April.
