Does anyone have any idea if there's any way to treat feline dandruff?

I can't do anything about the air in my apartment being dry, especially with it being winter. I'm hoping there's something I can do to help the dry skin, and dandruff, my cats are suffering from.

Poor kitties are itchy.

I take fish oil gel capsules myself, and daily will poke one with a pin and squeeze out the oil onto their food. We brush cats a lot more during the winter. Make sure there is always clean, fresh cold water. Our cats even like an ice cube floating in it.

Can you get a humidifier?

Humidifiers don't cost much. We go through several gallons of water a day in a humidifier and it's still dry.

I don't have the money for a humidifier, right now.

I can try to get fish oil capsule, though. They always have fresh water. Although, if unky had his way, everything in my house able to hold water, would.
