My kitten vomited a worm after deworming. Should I re-worm her?

That looks like a roundworm. You need to deworm a cat every two weeks when they have worms due to the life cycle of the worm. The deworming treatment will not kill eggs. So the first treatment kills the adult worms present while the second one kills the worms that had not yet hatched at the time of the first deworming. Give Max a deworming treatment now, another in two weeks, and then another two weeks after that to be safe.

Submit the worm and a stool sample to your veterinarian to identify the specific parasite. You may need to repeat the deworming and then use a monthly preventative. The dewormer likely did not clear all the parasites, since it only affects the parasites at a certain stage in its lifecycle.

No need to apologize for posting again, we are here to help :-) Even though Misty has been dewormed once, it will take more than one deworming treatment to kill all the worms. The first deworming treatment kills all the adult worms, but it doesn't kill the eggs. That's why you need to give a second deworming treatment two weeks after the first. This second treatment will kill the worms that had not yet hatched at the time of the first treatment. I would give her another deworming treatment in a week, and then if that still doesn't clear up the diarrhea, have her seen by a vet. You are correct her kittens can get worms from her, and they should be dewormed as well. I hope this helps!

If he vomited within 2 hours, I would recommend calling your vet to let them know and picking up a second dose to repeat the treatment. It likely didn't have enough time to absorb in to Allyson's system.

Yes - a wormer designed for roundworms is the best option. Be sure to follow all directions as regards minimum age for use (some should not be used before 9weeks etc), correct species and weight and to repeat treatment at the correct frequency. If she is vomiting frequently, a spot on medication may be more useful to ensure she does not vomit the oral treatment before it has time to work. Your vets office can advise on the most appropriate product available in your area

Great question! When kittens have worms, it typically takes two deworming treatments given two weeks apart to kill all the worms. The first kills the adults already present, which the second kills the adults who had not yet hatched from the eggs at the time of the first deworming treatment. I would give you kittens another deworming treatment now, a second two weeks after the first, and then they should be dewormed every three months regularly. If deworming them again doesn't help with the scooting behavior, then I would take them back into the vet. Good luck, I hope this helps :-)

Due to the lifecycle of tapeworms, more than one treatment is needed to kill all the worms. At least two treatments need to be given two weeks apart. The first kills the adult present, while the second kills the adults that had not yet hatched at the time of the first treatment. You need to take your kittens back into the vet.
