Question
my cat has developed a lot of dandruff on his back .  It gets heavier towards the tail.  His coat looks dull.  He suffers from IB and is on budesinide for over a year.  He also takes theodur for asthma.  I've been wiping him down with plain water since this started and brushing him a little more often.

Answer
Hi Jo-Ann,

It's good to keep up with the brushing. I recommend using a brush with rubber tips on the bristles to help message the sebaceous glands. This may help to stimulate the release of sebum, an oily substance to moisturize the skin, which may help reduce dryness, which can be common this time of year. It can also add back some luster to his fur. Then, finish with a slicker brush, which will distribute the oils throughout the fur and comb out loose fur and dandruff.

However, I would also suggest that he receive a check up. Excessive dandruff and a shabby coat is often a sign of a medical condition. If his IBD isn't well-controlled, malnourishment could be the problem. If it is well-controlled, a thyroid condition, kidney problems or even diabetes may be to blame. Diabetes can (rarely) be induced by the use of corticosteroids like budesonide. These conditions cause a loss of nutrition, and skin and coat condition can suffer. Some standard blood tests might be in order just to rule these out. During the exam, the vet can also check for skin conditions that might be the cause. Since your cat is clearly prone to inflammatory conditions, it could be possible he's experiencing some autoimmune reaction that's causing flaking of the skin. There are even mites called cheyletiella which resemble dandruff so much, they are nicknamed "walking dandruff." These are uncommon in cats, but could still be a small possibility.

If all checks out well at the vet, consider adding a healthy skin and coat supplement to his diet. Anything with Omega-3 fatty acids is a good choice. Ask your vet if they carry Dermaquin by Nutramax, or any other skin supplement. It's also available through online retailers and some pet stores.

Good luck!
