The Symptoms of Roundworms in Cats

Feline roundworms, also known as ascarids, are internal parasites that affect cats. There are two common types of feline roundworms: Toxascaris leonina and Toxocara cati. Kittens can get roundworms from drinking milk from an infested mother, as the roundworm larvae pass through the mammary glands to the kitten. Cats can contract feline roundworms from coming in contact with stools or food that has become contaminated with eggs of roundworms. It is also possible for a cat to get roundworms from coming in contact with or ingesting intermediate (also called paratenic) hosts, such as roaches, rodents, birds and even earthworms. Roundworms do not attach to intestinal walls. They swim around inside the gastrointestinal tract before migrating to the feline's lungs, liver and muscles, before returning to the intestines to complete their life cycle. They can grow up to 6 inches in length. Roundworms can be a significant cause of illness in adult cats and can cause death in kittens. Also, roundworms can be transmitted from felines to humans, particularly people with weakened immune systems, and may cause blindness and central nervous system disorders.

  1. Pot Belly

    • Kittens and cats suffering from roundworms may develop distended bellies.

    Vomiting

    • Stomach discomfort, such as vomiting, may be present in cats that are infested with roundworms. Occasionally, felines may vomit up whole worms or parts of a roundworm.

    Diarrhea

    • Cats may suffer from loose and frequent stools if they have roundworms. They may also discharge eggs and worms in the stool. Diarrhea can lead to dehydration, which can be fatal to kittens and elderly cats.

    Altered Appetite

    • Felines may experience a decrease in appetite when infested with roundworms. This may be in part due to the size of the roundworms and the space they are taking up in the stomach and intestinal regions.

    Stunted Growth

    • Kittens may have slowed or stunted growth due to roundworm infestation. They may not gain weight at a normal rate and may not reach developmental milestones as predicted.

    Intestinal Blockage

    • As roundworms continue to multiply and grow, they can block intestines, causing serious health problems to felines and even death to kittens and elderly cats.

    Change in Coat Appearance

    • A feline that has roundworms may acquire a dull, coarse coat. Muscle loss due to listlessness may also occur.
