My cat pumpkin has long fur and I try to comb her as much as I can but she does not like it and attacks the comb and my hand, I can get the fur on her back and sides if I am careful but it is hard to get the fur on her underside and she tends to get clumps under her front legs, any suggestions on how I can get her to let me get her underside and what to to about the clumps, they are not big, usualy about dime size.
