Thank you for your inquiry to Drs. Foster and Smith. We have an informative comparison chart to help you decide which type of brush or comb best suits your cat's grooming needs.http://www.drsfostersmith.com/pic/a...
Some cats love to be groomed - giving you excellent "bonding time" and a beautiful cat. Conversely, some cats seem to despise brushes and combs, and should therefore be groomed only on an "as needed" basis.
The FURminator® deShedding Tools for Cats Large 2.65", 9B-74117 is a popular item you may want to try. Gently removes undercoat, loose hair, and environmental debris. To remove clumps you may want to try the Mat Removing Tools for Cats Matbreaker (6-1/2"), 9B-3883. One of the reasons pet owners avoid grooming is to avoid dealing with mats. As a rule, mats bigger than your thumb need special care. Your pet's skin is very delicate and thinner than yours, so if your pet is severely matted, it may be wise to consult a professional groomer.
