A Better Cat deShedding Tool: FUR4's patented design is made specifically for Long Hair Cats to remove loose fur and reduce shedding. Safer: Eight SafetyNubs prevent scraping and damage to your pet's skin. Unlike other dog deShedding tools that use harsh metal blades, FUR4 uses an advanced composite carbon fiber for a safer deShedding experience. Gentler: Four deShedding edges spread out pressure for a more comfortable grooming experience for you and your pet. Multiple deShedding edges gently remove loose hair and undercoat without cutting or damaging your pet's topcoat.
