Do Cats Poop Out Worms After Being Dewormed?
One of the most common concerns for cat owners who have administered a deworming treatment is whether or not their feline will visibly pass worms in their feces afterward. Understanding the deworming process, its effects, and what to expect can ease anxiety and ensure the health of your pet.
What Is Deworming?
Deworming is the process of eliminating internal parasites from the body. In cats, this most commonly targets worms such as:
- Roundworms
- Tapeworms
- Hookworms
- Whipworms
Deworming medications can come in tablets, topical applications, or liquids. Once administered, they either paralyze or kill the worms, enabling the body to expel them through digestion.
Will My Cat Poop Out Worms?
Yes, it is completely normal for a cat to pass out worms in their stool after being dewormed. This usually occurs within a few days of treatment and is evidence that the medicine is effectively working. Here's what you might notice:
- Visible worms in stool or around the anus
- Mucus-covered or partially digested worms
- No worms but improved health (not all dewormers expel worms visibly)
What Types of Worms Are Seen?
The most commonly seen worms in a cat’s feces post-treatment include:
- Roundworms: Look like spaghetti strands; may be noticeable in the feces.
- Tapeworms: Segmented and rice-like in appearance; segments may be found near the anus or in bedding.
- Hookworms or whipworms: Often not visible due to being smaller or dying in the intestines.
How Long After Deworming Will Worms Be Visible?
Most cats will begin to pass worms within 24–72 hours after receiving a deworming treatment. However, this timeframe may vary depending on:
- The type of worm
- The cat’s digestive health
- The deworming product used
Is Seeing Worms a Sign the Treatment Worked?
Yes, seeing worms in the stool is generally a sign the treatment is effective, as it shows the parasites are being expelled from the body. Even if you don’t see worms, it’s possible the treatment killed them and they were digested or decomposed internally.
What Should I Do After Deworming My Cat?
Here are some important steps to follow post-treatment:
- Monitor your cat’s stool: Watch for presence of worms and consistency of bowel movements.
- Maintain cleanliness: Change the litter box daily and clean surfaces to prevent reinfection.
- Administer follow-up doses: Some deworming therapies require a second dose after a few weeks.
- Schedule a vet checkup: Follow up with your veterinarian to ensure all worms have been eradicated.
Can Cats Get Reinfected After Deworming?
Unfortunately, yes. Worm eggs can remain in the environment and re-infest your cat if hygiene and prevention are not maintained. Prevent reinfection by:
- Using monthly preventatives
- Maintaining a clean living space
- Keeping your cat indoors or monitored outdoors
When to See a Vet?
Contact your vet if your cat shows signs of continued infestation or adverse reaction after deworming. Symptoms include:
- Persistent diarrhea or vomiting
- Lethargy or behavioral changes
- Severe bloating or loss of appetite
Final Thoughts
Seeing worms in your cat’s stool after deworming can be unsettling, but it's a normal and positive sign. Timely deworming treatments, regular vet checkups, and maintaining cleanliness are essential for your cat’s health. Stay informed and proactive to ensure your feline friend remains parasite-free and healthy.
