onze katten hebben nooit last van haarballen....rexen....

maar 'k vond dit op bp via Dory, miss heb je hier wat aan?
gewone vaseline....
Petroleum jelly's molecules are too large to be absorbed by the intestines; it passes through the cat unchanged, and is perfectly safe. I fed my cat, Spirit, plain Vaseline every day her whole life — she lived to be well over 20, so I feel confident in saying it didn't hurt her at all.

Hairball Remedies for Cats
You can use a commercial remedy like Petromalt or Laxatone, but I have several natural remedies that will work and won't cost a trip to the pet shop. Feeding your cat a bit of butter or margarine can do the trick, or you can use a dab of petroleum jelly on their nose. One teaspoon of mineral oil will also work, and you can also feed about one-quarter to one-half a teaspoon of mineral oil every couple of weeks, as a preventative measure.
