How to Treat a Cat With Stomach Worms

Cats commonly get many kinds of worms. Stomach worms, also called physaloptera and ollanulus tricuspis (two different worm types), however are not very common, according to Cat Health. Sometimes a cat may instead be infected with roundworms, which are then vomited, making it appear the cat has stomach worms. Roundworm are actually much more common, indeed they are the most common worm according to Peteducation. Piperazine is the ingredient found in most over the counter roundworm medicines. Unfortunately, this will not kill physaloptera or ollanus tricuspis.

Instructions

    • 1

      Take the cat to your veterinarian for a diagnosis first. If the cat indeed has stomach worms and not roundworms, there may be no reliable treatment, however, wormers containing fenbendazole may help.

    • 2

      Mix the fenbendazole in with your cat's food, if the veterinarian has prescribed this medicine--it is available only by prescription. Wormers are dosed according to weight. The veterinarian will tell you how much to give.

    • 3

      Continue the treatment with this wormer over the next few days. Website Marvistavet advises that this drug is used for three to five days.

    • 4

      Give the cat an over-the-counter roundworm medicine (if your vet says it is okay) to kill worms if he or she ruled out stomach worms and believes the cat simply has roundworms.

    • 5

      Mix the roundworm medicine with a very small amount of aromatic food (the medicine is a liquid). Cats are very picky, typically, and despite what the medicine's label suggests, most cats balk at foods that smell medicated. If your cat likes fish, choose the strongest smelling fish to cover up the odor of the medicine.

    • 6

      Make sure the cat gets the entire dose. Repeat the dosage after two to three weeks (check the label) to kill roundworms that remain. Roundworms go through stages in the cat's body and those not in the intestinal tract at the time of the initial medicating will not be removed with the first dose.

      Observe the cat's stool and any vomit closely. Consult your veterinarian if you are still observing worms.
