Treatment is by lubricating the gastrointestinal tract so that the hairball passes unobstructed into the feces. Many preparations are available. One of those is Laxatone®. Do not use petroleum jelly. Over time, it will bind fat soluble vitamins (D, E, K and A) causing a deficiency in them. The majority of hairball preparations available are fortified in these vitamins. The easiest way to get a cat to ingest the product is to put some on the paws of the front feet. Most cats hate anything stuck on them and will lick it off. Using a finger or tongue depressor, rub some on the roof of the cats mouth. The animal will act like it is gagging but the product will melt and the cat will swallow it. Hill's® Science Diet Adult Mature Cat Hairball Control diet is also employed to slow down the development of hairballs.
Treatment of trichobezoars in the colon are sometimes relieved by enemas. If that fails, surgical intervention takes place and the obstruction is relieved.
Prevention also plays a big part in hairball control. All cats should be brushed and combed on a regular basis. If the cat will tolerate it, shampooing will also rid the cat of loose hairs and dander.
