Thanks for reaching out with your concern. When a cat vomits after receiving deworming medication or flea/tick prevention, it can be due to a few different reasons. One possibility is that her stomach is irritated by the medication, which is not uncommon. Another reason might be that the medication was given on an empty stomach, which can sometimes be harsh on her digestive system. It's also possible that your cat could be sensitive or allergic to one of the ingredients in the medication.
To help soothe your cat's stomach at home, you can try offering small, bland meals like boiled chicken or plain rice; this can be more gentle on her tummy. Make sure she has access to fresh water to stay hydrated, especially if she's been vomiting.
Keep a close eye on her for signs of continued distress, such as repeated vomiting, diarrhea, lethargy, or loss of appetite. If any of these symptoms persist, or if she starts showing signs of a more severe reaction like difficulty breathing or swelling, it's important to consult a veterinarian promptly.
If you're still concerned or would like to discuss this further, consider booking a video consult with Dial A Vet so we can evaluate your cat’s symptoms together and offer more personalized advice.
