Anyone use a furminator?

It's springtime here and I have two shedding cats, so it's Furminator time.  They adore being groomed and this certainly does get rid of a lot of loose hair.  After I've given them a good going over I wipe them down with a very slightly damp cloth to remove the loose hairs still on them (not their all-time favourite thing, but they put up with it )

Trouble is I've noticed Nilah is throwing up furballs.  Big ones.  I'm not sure whether this is just because she's shedding a lot, or whether the furminator is bringing to the surface but not removing a lot of hair.

Does anyone have any experience with them and could shed some light on this? 

BTW, I'm careful to remove all the hair I remove as Nilah will actually eat it! 

If u give them a good going over with adamp cloth after, I would think that gets the loose hairs. At one point I followed furmination with a rubber brush which used static to grab the loose hairs. I think it's specific to a cat to get hairballs. My 2 boys never ever hack up hairballs. My girl would cough up multiple hairballs on bad days. She did shed more than the boys though. Maybe try more often than once a day.

The rubber brush idea is excellent.. I'll try that, thank you.

we use the furminator on our long haired girl, she loves being brushed but just puts up with the furminator. She practically never coughs up hairballs, it has only happened once in her two year long life so far. I feel like the furminator gets 85% of the fur it should take, the rest we have another soft bristle brush for. 

I have a Furminator - an OLD one and there is a definite difference between the old and the new. I've had it for many years now and love it. I bought it for Felix, who sometimes gets matts behind his back legs and hates to have them out. The Furminator gets them out quickly and painlessly as it breaks them up gently. If the cat is having hairballs after being brushed it is likely because she is grooming herself to put her coat back in order. Giving her hairball paste or treats when you're finished grooming her can help prevent her from throwing up the hairballs.
