That's it! I have had it with these MF'ing hairballs on my MF'ing carpet!?

I have this problem occasionally with my cat, in addition to the hairball food I sometimes will give her the hairball goop that you smear on their foot and they lick it off, it will usually stop her from hacking for a few months before I have to do it again. I don't know if she just gets like a "super monster" hairball and that helps get it out or what but it seems to work well for me, because like you said they have to go straight for the carpeted areas. I have hard wood floors in my entire house except for the master bedroom and that is where she chooses to leave me all her surprises.

Every few days won't do it. He's got long fur, it needs to be brushed daily. Just like your hair does.

Short haired cats get hairballs too, but the longer the fur, the faster the hairballs form. Just start brushing on a daily basis and you'll see improvement.

The reason they use the rug is so their back feet don't slide when they barf.

I am not sure what type of brush you are using, but you need one with prongs on one side, and a regular brush on the other. You use the prong side to get off undercoat, and the regular brush to then take off any surface fur you have dislodged.

With a cat that has longer hair, this has to be done almost daily.

Ironically, I have found that sometimes the more you groom them, the more "presents" they provide for you.

With a Persian you need an undercoat rake and he should be brushed daily. I shouldn't think the hairball control science diet will do any good at all - none of the other science diets do!!!

First by brushing him once a day very very well you will prevent 60-70% from getting in his stomach.

Next buy some cat grass and let her eat that.

Grasses help them pass and digest the hair.

Grooming will help you the most though. If you have the time to do it morning and night it will help her greatly.

well really if its a long haired cat then your just going to have to get used to it, its in there nature to lick them self and barf the hairball out, if your REALLY tired of it I suggest you either trim your cat every once in a while or get yourself a short haired cat

Put him outside to eat some grass.

If you arent comfortable letting him out on his own, then get a cat harness and let him outside for a bit.
