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!

My cat has had diarrhoea and been sneezing for past 4 days was wondering if I should take her vets as it mite be something serious and she has 5 5week old kittens with her and don't want them to catch it
Hi and thanks for using Boop by Petco! Sorry to hear about Misty. Most likely you are dealing with intestinal parasites passed from the queen to the kittens and then back to the queen. All kittens are assumed to have hookworms and roundworms from their mother. They get infected while in the uterus and while they are nursing. Thus, kittens should be dewormed every 2-3 weeks starting at the age of 2 weeks old. The queens get infected from the kittens after they start shedding the parasite eggs. I'm sure a good deworming would help Misty get back on track. Try deworming and go from there. The drug to use is pyrantel pamoate which kills rounds and hookworms. You mention something else that is going on which is sneezing. The queen cat often carriers for life the viruses that cause upper respiratory diseases and after she queens, she will break with the viruses and start shedding them to the kittens. Most likely that is causing her sneezing. I would monitor her and the kittens f

I have a pair of 18-month-old kittens they were treated for worms about a month ago and no problems with their anal sacs were found during the exam for worm treatment. but they still drag their butts on the floor from time to time. should they go bac
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 :-)

Our 6mth old kitten has just vomited. It looked like a small fur ball but there was also something that looked like a worm. She was wormed 6 weeks ago. Should I re-worm her. She weighs 2.56 kgs.
Poor kitty. Typically most pets require a second deworming 2 weeks after the 1st to treat for re-emergence of worms because of their life cycle, so yes it is appropriate to deworm Molly at this time. Pyrantel palmoate or Fenbendazole are typicallly used. This should clear things up for good, as long as she doesn't get re-infected from exposure to the outside. Keeping her on a monthly flea preventative like Revolution can also help prevent re-infection because it contains an intestinal dewormer in it as well.

I have bought kitten dewormer from Walmart and I've wormed him twice. What should I do he still has worms and he always has diarrhea.
You are not giving the correct medication. If you are seeing tapeworms, small flat worms or rice like segments near the anus, then you need a prescription dewormer from your veterinarian. I recommend taking a fecal sample in and have them look for parasite eggs under the microscope. Then they can make sure they give you the proper medication. Once Smokey gets rid of the intestinal parasites probably the diarrhea will stop. Thanks for using Boop by Petco to help you care for Smokey.

Please help! I took my kittens to get dewormed at the vet a couple of weeks ago. And after assuming the worst I felt that they weren't sick anymore. Their stool returned to normal (no blood or tapeworms as I could see), and they stopped vomiting. The
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.

My cat has been dewormed once only... i missed the second appointment... is it important to have them dewormed coz there isnt any worms in there stool anymore.... also do you think they having diarrhea is a reason they didnt get dewormed??
Thanks for using Boop by Petco! 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!

9 week old kitten. Had been dewormed twice before we took her home last week. Having diarrhea. Only like wet food and people food. Won't eat dry kitten food. How do we stop the diarrhea? Thanks.
Even though Coco has been dewormed twice she could still have intestinal parasites like coccidia that would not be susceptible to standard dewormers. Other causes of diarrhea include infections or food sensitivities. I would recommend seeing a vet for a fecal analysis. If it is normal you can discuss diet changes that could help, like increasing fiber or trying a limited ingredient diet.

What is this kind of worm? my cat is throwing up mucus and these occasionally and has been wormed for roundworm when I initially got and then again 30 days later please help stray pick up not a lot of money thank you
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.

I gave a street cat shelter when she was pregnant. She gave birth to 3 kittens. Recently I took them to a vet for the first time. He gave them deworming medicine. It’s been 7 days till then. Mama cat did not eat anything for 2 days and ate only a few
This should pass within 48 hours or so. I recommend to call your veterinarian and ask about a probiotic. That can help to reset the bacteria within the intestines. A bland diet can also help. Your vet may sell a special diet or you can try 25% boiled white meat chicken and 75% boiled white rice. This should all be plain.If the diarrhea continues beyond 48 hours or if they are getting worse instead of better, I recommend to have them examined again. I hope this helps. Please feel free to post any additional questions.

I rescued a stray kitten that was about 4 months old. Since I brought her home she has pooped non-stop. I thought it could have been worms but when I took her to the vet, she was given de-worming medicine and for about a week, she had blood and worm
I hate to hear that. It’s possible she is still having issues with worms (some heavily infested pets will require multiple treatments) or that she has another problem like bacterial imbalance or a dietary problem. I recommend to rule out the possible causes by having her stool examined again. This will help determine if worms or bacterial imbalance is present. then she can start the appropriate treatment. I hope she starts feeling better quickly.
