Cat threw up spaghetti-like. Gave meds, but no worms in stool. Working?

Hello and welcome to Petco Pet Education Center, formerly Petcoach. As long as the worming tablet was in for about 30min then you don't need to give a second tablet. However a 2nd tablet, as long as it is one designed for cats, won't cause a problem. They have very high safety margins. Best of luck with your kittens!

It could be they had worms previously and you didn't know it. It sometimes can take until there is a heavy infestation of worms for you to see them in vomit or feces. Typically only eggs are passed in the feces, and those eggs can be seen with a microscope, not the naked eye. You have to repeat the deworming treatment to kill all the worms. The first one treats the adults already present, while the second in two weeks will kill the ones that had not yet hatched at the time of the first treatment. Hopefully you will stop seeing dead worms in the next couple of days, but it means the treatment is working. Best of luck.

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.

Thanks for using Petco Pet Education Center, formerly Petcoach! Parasites is certainly a good reason for diarrhea. I highly recommend you go in for that second appointment to get the dewormer. The reason is most of the time, it is needed to follow up on the initial deworming dose to be actually effective for most parasites. Good luck and have a great day!

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.

That means the medication is working, as you can frequently see dead worms after a treatment. Godive will need another deworming treatment in two weeks to kill all the worms, and I would give her another dose then.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Hopefully seeing the worms pass in her stool means that the medications are working. I recommend rechecking a stool sample in 3-4 weeks to make sure there are no eggs present
