What to feed a cat whose hair and skin seem a bit dry?

I have a six-year-old female cat. Spayed. Her hair and skin feel drier than my other three cats' does.





She will eat ONLY dry food. The others eat a combination of


canned and dry. She drinks as much water as the others do.





She is not losing her hair at all, and does not have any rashes or bare spots. Her hair is very thick, all over - just dry.





She does not appear to be ill in any way.





Should I put a little vegetable oil on her dry food?





I'd rather treat her from the inside (via diet) than apply something to her fur from the outside.





Any suggestions?|||If you go to a pet store, there is a product that you can give your cat that restores the oil in their bodies...it also has other things added that can help your pet. I found it to work great and I own 8 cats. You don't have to give it as often as it recomends...use less than what it tells you.|||well what i think you should do is ask a vet|||ask a vet and buy your cat some of that cat food that says it will give your cat a smooth and silky coat|||How about applying hair conditioner than human use?|||If your not feeding your cats science diet, you should, you can find it at any vet or pet store... if you'd rather do supermarket, feed them iams or purina.. all the other stuff is like feeding them mcdonalds.... if that doesnt clear it up get some omega-3 fatty acid liquid for dogs and cats.. your vet will have this for sure, if the petsore doesnt.. squirt that on the poor cats food.. dont worry they love love the taste :)|||There is a product that you can buy from your vet called DermCap Liquid. It smells really fishy and you can either squirt a little in your cat's mouth or mix with a little of her dry food.





When I fed Hairball food to my cats, I noticed that their hair got pretty oily so, that may help.|||It could be the time of year if you are running heat in your house. My cat gets a little more dander than usual in the colder months. You could add water to the air in your house by running either a vaporizor or a humidifier. Also some cats are just softer than others like people they are all different.
