Bengal cat sick, not eating after deworming. What should I do?

Thank you for submitting your question regarding your kitten. If he is not improving, then I recommend that he has a further work up. He should have fecal testing, blood work and x-rays of his abdomen to determine the cause of his vomiting and inappetance. Kittens can react to deworming medication, but it is typically a short lived reaction. It worries me that he is still ill. There is likely another another disease process present. In the meantime, encourage him to drink so that he does not become dehydrated. I hope this information helps!

It is possible that the worms were the reason why he wasn't eating, and the deworming treatment itself can make him feel nauseous and unwell. It's the result of the dead worms moving through his GI system. I would recommend offering him a bland diet of boiled white meat chicken (no bones) in small amounts to try to tempt him to eat. You can also soak his dry food in tuna juice, or offer him gently warmed really smelly wet food, such as sardine or fish based. If he still isn't eating in the morning, I would have him seen by the vet again. It will take at least two deworming treatments to kill all the worms.

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! Sorry to hear about Laila. I would advise taking her to your vet immediately if she won't eat. She may be running a fever, have some pain/discomfort, etc. Your vet can take a detailed history, perform an examination, and recommend a diagnostic/treatment plan. Once a diagnosis is made a sound treatment plan can be implemented. You can try cyproheptadine if you have it but I'm concerned she may be running a fever from a viral infection, not sure how much the cypro will help. The normal dose is 2 mg every 12 hours in cats. Good luck

Poor Frodo! Some cats do vomit during deworming due to the strength of the medication combined with the parasites moving through the GI system. These side effects should only last a few days, so if it's been longer than that, I would be concerned that it could be due to something else, such as a GI illness, a foreign body, or pancreatitis. I recommend withholding food for 12 hours, then feeding a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the vomiting continues in the absence of food, he vomits the bland diet, develops diarrhea, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away.

Thank you for visiting Petco Pet Education Center, formerly Petcoach. What you describe definitely sounds like tapeworms. I am sorry to hear that Toby sounds like he is having an adverse reaction to the tapeworm medicaiton. This sounds serious. I would highly recommend taking Toby in to your vet to have him treated for an adverse reaction, which includes fluids for flush out his system and and symptomatic treatment. It’s best to take him in right away if possible. I hope that your pet Toby is able to make a full and speedy recovery. Best wishes and take care.

I'm sorry to hear about Nylon. If he was just recently treated and is now having a severe reaction to the treatment it is best to contact the vet that treated him and bring him back in for care immediately. They may need to place him on IV fluids or other measures to reverse any reactions and get him recovering. If your current vet is not available, seeking out an emergency vet in your area is best.

If Gizmo hasn't eaten in 3 or more days, she is at risk of developing serious liver related complications. At this point in time, she needs to be examined by your veterinarian. Blood work should be submitted to assess major organ function. Bring the medication your gave her (or the package it came in) to your vet for examination as well. She may require hospitalization and supportive care until she is eating on her own. Discuss payment plans with your vet as well as alternative financing options such as Care Credit (www.carecredit.com). You may also seek financial assistance through Red Rover (www.redrover.org).
