What Are The Side Effects of Deworming A Cat?

Rarely will your cat will experience side effects caused by it being dewormed. The side effects typically appear after or within 24 hours.



However rare these side effects are, some cats may exhibit apart from diarrhea the following side effects;

1. Vomiting

Some cats may react to the deworming medications, which may cause them to vomit. In case your cat vomits within one hour after being dewormed, please take it back to your vet for further management.

Note excessive vomiting in a cat may cause it to become dehydrated.



Also, it’s possible that your cat’s deworming meds may not have been effective if it vomits within one hour, so there might be a need to deworm it again.

2. Loss of Appetite

Anxiety combined with the physiological changes taking place in your cat’s gastrointestinal tract is some of the causes that may cause it to lose appetite. This side effect resolves on its own within 3-4 days.

During this period, you can help improve your cat’s appetite by giving it appetite stimulant medications (which should be prescribed by a certified vet) or feeding it with fresh and clean catnips.



Catnips are natural appetite stimulants for cats.

3. Increased/excessive salivation

Anxiety, the sour taste of the drug, and not fully swallowing the deworming medications can cause your cat to produce excess saliva. This side effect may last for 2-3 days.

Conclusion

Cats, just like any other animal, are susceptible to worm infestation. Most often, cats who have worms may not show any signs or symptoms of worm infestation such as weight loss, diarrhea, vomiting, patchy skin, coarse or dull and unhealthy coat, unexplained weight loss, and reduced level of activity.

After deworming, your cat may experience diarrheal episodes, which should resolve on their own within 2-3 days. Other side effects of deworming your cat may include vomiting, loss of appetite, and increased saliva production.



For a healthy and happy cat, it’s crucial that you always adopt your cat from a reputable breeder who strictly follows a deworming cat schedule.
