Size 2.5" (approx. 6.3 cm) for Cats or Small Dogs Or use this on your horses' legs or face, or on small dogs. Same concept, just smaller size. The cats LOVE it they are saying. It works like a "bionic cat tongue" to remove all that loose kitty fur.... It makes cat grooming that much easier! This Cat Grooming Brush handle is constructed of poplar wood waterproofed with a "green" water-based lacquer. The metal blade is a design exclusive to SleekEZ.
