Is it normal for a cat to get diarrhea after taking dewormer, or should I be concerned?

I gave my cat a dewormer yesterday and since then, she's had diarrhea which has me a bit worried. It's happened a few times now, and she seems more lethargic than usual and isn’t interested in her food. I understand that medications can have side effects, but I'm unsure if this reaction is normal or if I should be doing something more.

Answer

Diarrhea and lethargy can be side effects of deworming medication in cats, but it's important to monitor her closely and consult a vet if her condition doesn't improve soon.

  • Monitor for dehydration (gums should be moist, not sticky or dry)
  • Watch for continued lethargy or any decrease in activity levels
  • Check if she drinks water and eats, even if it’s just a little bit
  • Notice if the diarrhea persists or gets worse

While some side effects like diarrhea and reduced appetite can occur after deworming, these reactions are typically mild and short-lived. However, they can lead to dehydration or indicate underlying health issues if they persist. This is particularly important because cats can become dehydrated quickly due to their relatively small body size and unique dietary needs. Ensuring your cat stays hydrated and that any symptoms don't progress is crucial. If the symptoms don't improve or if your cat continues to be lethargic and refuses to eat, it would be wise to consult with a vet.
