The best way to use our deshedding brush is to first bathe your pet and dry them completely (your pet must be 100% dry). Once dry, brush out all of the mats and tangles. After your pet is fully detangled use our deshedding brush. Gently brush in the direction of your pet’s hair growth being careful not to scrape your pet’s skin. Keep a trash bag close to discard of the removed fur. Does it work on my short hair cat? Yes, both 2.5”and 4”blades can work well for short-haired cats and dogs. However,the blades aren’t designed for extremely short or long haired(<1.2 inches or >2.8 inches) pets. so if you order it before you realize your pet is with extremely short or long hair, please just return it instead leaving a negative review. By the way, the 2.5”would be a better size for cats. How often should I use this pet deshedding comb?
