I'm so sorry to hear about your loss. Losing a pet is incredibly difficult, and it's understandable to have questions and concerns following such a sudden event. While it's uncommon, some cats can have adverse reactions to deworming medications, especially if there's an underlying health issue or if the cat was heavily infested.
Reactions can vary from mild digestive upset to severe allergic reactions or toxicity, depending on the product and health of the cat. Symptoms of a serious reaction might include vomiting, diarrhea, difficulty breathing, lethargy, or seizures. It's also possible the sudden passing was unrelated to the dewormer and due to another medical condition.
To understand what happened, consider any prior health changes or stress your cat may have experienced. If they were eating less, acting differently, or had any known health issues, these could provide clues.
For future pet care, always ensure dewormers are the correct dosage and type for your cat's age, weight, and health. After administering any medication, monitor for unusual behaviors or reactions—especially during the first few hours.
I highly recommend booking a video consult with one of our vets at Dial A Vet to discuss your cat's situation in more detail. They can offer guidance and help you make sense of this troubling event.
