Cats are adorable companions. They curl up on your lap, purr to comfort you, and make even the dullest day brighter. But while their presence is delightful, there’s an often-overlooked health risk—worms. Yes, your beloved cat can give you worms, and understanding how this happens is essential for your well-being and theirs.
In this guide, we’ll explore how cats can pass worms to humans, the types of worms involved, symptoms you may experience, prevention tips, and what you can do to keep yourself (and your feline friend) safe.
What Are Worms in Cats?
Worms are intestinal parasites that live inside your cat’s digestive tract. They feed off the nutrients your cat consumes, sometimes causing illness. While cats often show minimal symptoms, these worms can spread to humans through direct or indirect contact.
Some of the most common worms in cats include:
- Roundworms
- Hookworms
- Tapeworms
- Whipworms (less common in cats but still possible)
When these worms or their eggs are accidentally ingested or come into contact with human skin, they can cause infections.
How Can Cats Give You Worms?
There are several ways your cat can transmit worms to you. The transmission depends on the type of worm and how it spreads. Let’s break it down:
1. Direct Contact With Feces
Most worms in cats are spread through their feces. Worm eggs are passed in stool, and if you accidentally touch contaminated litter or soil, you might ingest the eggs. Something as simple as cleaning the litter box without washing your hands properly could increase your risk.
2. Contaminated Surfaces
Cats often walk around the house after using the litter box. They may carry microscopic worm eggs on their paws and transfer them onto carpets, furniture, or even your bed. If you touch these surfaces and then touch your mouth, you can accidentally ingest the eggs.
3. Close Physical Contact
Snuggling with your cat is usually safe, but if your cat has worm eggs stuck in its fur (especially around the tail or anus), you may come into contact with them. Children are particularly vulnerable because they tend to cuddle pets without thinking about hygiene.
4. Fleas as Carriers
In the case of tapeworms, fleas act as intermediate hosts. If your cat swallows a flea while grooming, it can develop tapeworms. Humans, especially children, can also accidentally ingest fleas and become infected with tapeworms.
5. Outdoor Exposure
If your cat roams outside, it may come into contact with contaminated soil, dead animals, or other infected pets. Outdoor cats are more likely to pick up worms and bring them into the home, putting you at risk.
Types of Worms Your Cat Can Pass to You
Not all worms in cats can infect humans, but some are zoonotic (meaning they can cross from animals to humans). Here are the main types:
1. Roundworms (Toxocara cati)
- How they spread: Through cat feces containing eggs.
- Risk to humans: In humans, roundworm larvae can migrate through the body, a condition known as toxocariasis. They can cause:
- Eye damage (ocular larva migrans)
- Organ inflammation
- Fever and fatigue
Children are particularly at risk if they play in contaminated soil or sandboxes.
2. Hookworms
- How they spread: Eggs from cat feces hatch into larvae that can penetrate human skin.
- Risk to humans: They can cause a condition called cutaneous larva migrans, which leads to itchy, red, snake-like rashes on the skin. In rare cases, hookworms can enter deeper tissues, causing more severe illness.
3. Tapeworms
- How they spread: Through fleas. If a human swallows an infected flea, they can get tapeworms.
- Risk to humans: Tapeworms live in the intestines and can cause:
- Stomach discomfort
- Nausea
- Visible tapeworm segments in stool
4. Whipworms (Rare in Cats)
While whipworms are uncommon in cats, they can still cause gastrointestinal issues. In humans, they may lead to diarrhea and abdominal pain.
Symptoms of Worms in Humans from Cats
If you’re wondering whether you’ve picked up worms from your cat, here are some symptoms to watch for:
- Abdominal pain
- Nausea or vomiting
- Diarrhea or constipation
- Visible worms or worm segments in stool
- Itchy rash (common with hookworm larvae)
- Unexplained weight loss
- Fatigue
- Eye problems (in rare cases of roundworm infection)
Children may also complain of tummy aches or show irritability without a clear reason.
Symptoms of Worms in Cats
Cats don’t always show obvious signs, but keep an eye out for:
- Worms or segments in feces or around the anus
- Vomiting (sometimes with visible worms)
- Diarrhea
- Weight loss despite normal eating
- Bloated belly (especially in kittens)
- Dull coat and poor condition
- Scooting or excessive grooming around the anus
If your cat shows any of these symptoms, a vet visit is essential.
How Serious Is It If You Get Worms from Your Cat?
For most healthy adults, worms cause mild to moderate symptoms and can be treated with medication. However, the risk is higher in:
- Children – because they’re less likely to follow strict hygiene practices.
- Pregnant women – certain infections can be harmful during pregnancy.
- People with weakened immune systems – infections can become more severe.
Roundworms, in particular, can cause lasting damage if larvae migrate to the eyes or organs. While rare, such cases highlight why prevention is so important.
How to Stay Safe from Getting Worms from Your Cat?
While the idea of catching worms from your cat may sound alarming, the reality is that simple preventive steps can protect you and your family. Here’s how to stay safe:
1. Keep Your Cat on a Regular Deworming Schedule
- Follow your veterinarian’s advice for deworming frequency.
- Kittens need more frequent deworming, while adult cats typically need it every 3–6 months.
