Roundworms in Cats: How to Keep Your Feline Friend Safe and Healthy

Roundworms in Cats

As a cat parent, all you want is the best for your feline friend. However, despite your best efforts, your cat may still be at risk for one of the most common parasitic infections – roundworms. These creepy crawlies can cause multiple health problems for your cat, but fear not! With the right knowledge and precautions, you can keep your cat healthy and happy.

Let’s look into the world of roundworms in cats and learn what you can do to protect your furry companion.

What Are Roundworms in Cats?

Roundworms, also known as ascarids, are a common type of intestinal parasite found in pets. They are typically long, white, and cylindrical resembling spaghetti noodles, and can grow 3–6 inches long.

What causes Roundworms in Cats?

Roundworms in cats are transmitted when they ingest infected feces or prey animals or come in contact with contaminated soil.

Although kittens are most likely to get roundworms, cats of all ages are susceptible to infection. An adult female roundworm living in a cat’s intestines releases eggs that are flushed out into the environment through the cat’s feces. These eggs develop into infectious larvae.

A roundworm-infected pregnant cat can pass the infection to her kittens during pregnancy through the placenta. Kittens also get infected through the milk of an infected mother cat. Cats of any age can get the infection by ingesting the eggs from the soil or larva-infested rodents.

Symptoms of Roundworms in Cats

Symptoms of roundworms in cats can vary depending on the severity of the infestation. The signs of intestinal worms in cats include:

• Poor growth
• Diarrhea
• Loss of appetite
• Weight loss
• Vomiting
• Respiratory symptoms
• Bloated abdomen
• Intestinal Thickening
• Swelling of the duodenum
• Indigestion

In rare cases, a life-threatening situation may be caused by the bursting of the intestines.

Treatment of Roundworms in Cats

There are many oral and topical treatments available for cats that effectively treat roundworms. Multiple doses of treatments should be given on a schedule to kill all life stages of roundworms.

Treatment of roundworms in cats typically involves deworming products, which are designed to kill parasites in the intestines.

Here are some of the popular roundworm treatments for cats:


Profender is a potential treatment that works against multiple worm infections in 8 weeks and older kittens and cats.

It helps in controlling various intestinal worms like tapeworms, roundworms, and hookworms. Profender eliminates worms with a single dose and regular treatments should be given at an interval of every 3 months. This is safe to be used on pregnant and lactating cats.

• Clean litter boxes daily
• Use an effective disinfectant

End note
