Detangling combs with rolling pin teeth are good for releasing tangles and loose fur that can cause matting later on, all without puling at the cat's skin. "I like a detangling comb with two lengths of bristles, because it allows you to get into the coat much deeper and reach both the top and bottom coat," Drechsel said. These combs can also be useful in grooming harder-to-reach areas like the underarms and around the tail.
She also noted that the width between the bristles of the detangling comb that you choose should depend on the thickness of your cat’s coat. For instance, thicker coats common among breeds like British short hairs or Persians would do better with a wide tooth metal comb
to better glide through the fur without causing tension, whereas cats with thinner coats might do well with finer tooth combs
