My cat threw up after flea treatment. When should I see a vet?

It sounds as Gab is suffering from a gastrointestinal condition, possibly an infection. it could also be due to ingestion of a foreign body material. i would recommend taking him to the vet the first chance you get, he will need to be checked first, if the vet thinks it's a simple gastrointestinal infection he will need an anti vomiting injection, antibiotics and a special food for a few days in order to get better.

No, this is not normal. You did not say which product you used. Some are more likely to cause reactions than others (like Hartz or Seargants). I suggest you use some Dawn dishsoap and wash it all off of him immediately.

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Foot foot. I'm sorry she hasn't been well! So cats are very sensitive to flea treatments, and her symptoms seem to match up with flea treatment toxicity (except for urinating outside the litter box). It may be that the Frontline is causing her problems. I would wash off the Frontline now, give her a bath to get it off if you applied it within the last 24 hours. If it's been more than 24 hours, have her seen by a vet now. Depending on when you applied the Fronline, either wait a week (if the Frontline was applied in the last 24 hours) or two weeks since the application (if apply longer than 24 hours ago), then use a different flea treatment program like Revolution or Advantage. I would not use Frontline again. As for urinating outside the box, this could be due to feline idiopathic cystitis. Stress can bring this on, and a reaction to flea treatment can be stressful. Have her seen by a vet for this. I hope this helps!

Kittens can be given flea treatment at 8 weeks of age. One important thing to do is make sure the spot on treatment is for kittens only. You can't give dog flea treatments to kittens because cats have a higher sensitivity to the active ingredients in flea medications. Vomiting and diarrhea are signs of a both a mild and moderate to severe reaction to flea treatment, and I would recommend taking Simba into your vet immediately for treatment. These symptoms can get worse and lead to death if not treated promptly.

I would observe Archie. Usually, once the offending tablet is out of his body, the vomiting should stop. So he may try to vomit one more time and then that should stop. If he keeps vomiting then you should take him to a vet for an exam. I am not so happy with the Bob Martin Flea products, I would stay away from them and rather buy flea medication from the vet. You then have a guarantee that they are good quality and likely work better than the over the counter medication.

If Lilith ingested Frontline, there isn't much you can do for her at home unfortunately. She really needs to be seen by a veterinarian. They will at the very least give her some fluids to help hydrate her and flush the substance out. She may also need more treatments such as blood work and medication.

Yes, Sentry products are not recommended. If you need flea prevention you should get it from your vet. My recommendation would be to try and wash off that medication ASAP. Use Dawn dishsoap to wash the cats since it will cut through the oils in the skin. Be sure to rinse them thoroughly and dry them with towels (not hair dryers). If they start showing any other symptoms, especially neurologic symptoms, they need to get to a vet as an emergency. Hope this helps. Sorry this happened. Best wishes.
