Query: FURmination Nation

I am thrilled with the way my FURminator performs! I have 5 medium-to-large dogs, amd 4 indoor cats. I live in the mid-south and this time of year my animals shed like you wouldn't believe! The FURminator removes more hair in one stroke than any other brush/comb I have used...and I have used MANY in an effort to cut down on grooming time and frequency. The "medium" size works well on both dogs & cats. I am telling all my friends about this marvelous tool. Buy one. You will not regret it!
