Nibblers is a new product Dr. Freesh saw at the American Association of Feline Practitioners meeting. Kittens and young cats who like to chew on items and people may enjoy chewing on these instead. They can be refilled with catnip. Dr. Freesh has had patients who chewed on the owner's leather purses, belts, and shoes.
In the past, Dr. Freesh had the owners purchase thin small dog rawhide sticks for something to chew plus store shoes and purses where the cat could not get to them.
