How Do Cats Get Worms?

Cats get worms from birth as the worms are passed through the placenta from the mother’s body to the kitten. They also get worms by getting in contact with the eggs found in the faeces of infected cats. 

In some cases, cats can get worms after eating rodents that are infected with worms. Fleas also transfer worms to the feline’s body when they bite it. If cats eat fleas that are infected with worms, they will also get infected. 

Tapeworms, roundworms, and hookworms live inside the body and harm the internal organs. They deprive the cat’s body of the essential nutrients, so your cat will be in bad health.

Symptoms that your Cat Has Worms

Here are a few signs that your cat is infested with worms.

  • Your cat has blood or mucus in the faeces.
  • Seeing actual worms in faeces.
  • Vomiting and coughing.
  • Having dull fur and unhealthy skin.
  • Weight loss and loss of appetite.
  • The cat has a swollen belly.

Features of a Good Cat Wormer

Finding the best worm treatment will keep your feline in perfect health. Here are a few features that should be found in the best cat wormer.


You need to make sure that the formula is fast enough to kill all the worms in the cat’s body. This way, you can help the cat avoid the deadly consequences of living with worms. You’ll also be able to protect other cats in the house from future infestation. 

Easy Application

Worm treatments are available in several forms. Topical treatments are easy to apply, but you need to make sure that your cat isn’t allergic to the formula. 

Liquid formulas can be applied directly into the cat’s mouth. If your cat doesn’t like the taste of the formula, you can mix it with food or drinks. 

You can also choose tablets or pills that your cat will consume before or after meals. If the tablets are too big, you will need to crush them. 

Adequate Effect

Make sure that you’re picking the right treatment for your pet. Some formulas are designed for all types of worms, while others will only work for tapeworms. 

Suitable Age

You must check the age recommendation for the formula. Some treatments aren’t designed for kittens and can be dangerous or even fatal. Most treatments can be used if your feline is older than 6 weeks old or weighs more than 1 kilogram.
