What am I to do about my cats fur epidemic?!?

dry and pelleted food can make shedding worse and can cause dandruff and skin flaking, but when we had a siamese we ended up with six vacuum cleaners to get the fur off all the surfaces easily even when he brushed against your leg it looked like you had a fur boot on, you could pull the fur out by the handful all year and it made no difference even with daily brushing, we had to be vacuumed before we went anywhere
