In the UK, there are eight types of common feline intestinal worms. Most can be grouped as either tapeworm or roundworm.

It can be difficult to diagnose pets with these parasites, especially if you have a cat that does most of its toilet business outdoors. But there are a few telltale signs to always look out for.

Vomiting, diarrhoea, a lacklustre coat and losing weight are four really obvious signs that something is wrong, as well as a loss of appetite. These are often when the issue is more severe, though. The only way to observe in its early stages is spotting worms in faeces or around their bottom.

Unfortunately, even indoor cats can become infected with worms. Fleas and their eggs carry tapeworm – so you also need a quality cat flea treatment to completely keep them away.

To protect against worms, you need a quality worming treatment. You also need to clean bowls regularly using a pet-safe disinfectant, dispose of faeces correctly and keep sleeping areas clean too.

If left untreated, worms can cause suffering and even death. Keeping your cat protected against worms is essential, as is finding a good product to tackle any current infestations. Below are our picks of the best cat wormers, as well as our guide on how to find the one for you and your kitty.
