What is ringworm in cats?

This common skin condition is a fungal infection which feeds on the keratin in a cat’s fur, skin and nails. It’s called ‘ringworm’ because the fungus creates circular ring-like lesions on your cats’ skin, usually also associated with hair loss. These are often found on the head, ears, along the ridge of the back and on the front legs, but they can be present anywhere on the body.

How do cats get ringworm?

Ringworm in cats is highly contagious and is most commonly caught through contact with infected cats. It can spread rapidly in multi-pet households as it gets distributed via fungal spores on skin and hair that’s been shed. Ringworm is very common in kittens under the age of one as their immune systems are still developing.

To diagnose ringworm in cats your vet may conduct different tests, such as checking for fluorescence under a special UV lamp, taking a sample of your cat’s fur to analyse under a microscope, or a blood test. However, the most reliable option to take coat brushing samples from your cat to be sent for laboratory testing. While this option is generally the most accurate it does take the longest, and you may have to wait up to two weeks for the results.

This is because spores can be quickly spread throughout the home. For long-haired cats, your vet may also suggest that your cat’s coat is clipped in order to tackle the fungus and make it easier to wash them with the anti-fungal shampoo.

Additionally, you’ll need to decontaminate your home to help treat ringworm in cats. The fungal spores present in cat hair or skin will shed into your home and contaminate the environment. Pet hair will need to be removed from any furniture or carpets by vacuuming daily and hard floors will need to be mopped – you can ask your vet about pet-friendly chemical disinfectants that are safe to use. Any of your cat’s equipment such as bedding, brushes and toys which can’t be effectively cleaned and disinfected will need to be thrown away to avoid re-infection.

According to VCA Hospitals, these spores can live in your home for as long as 18 months. Therefore, this part of the treatment for ringworm in cats is essential or you may run the risk of your cat becoming infected again. If you have other pets in the home, ask your vet whether they should also be treated. However, never use medication prescribed for one animal on another pet as this can be very dangerous, particularly if they are different species.
