Are Fleas Dangerous for Cats?

Fleas are dangerous for cats and other animals because they can quickly spread from one host to another and cause other health-related problems. Fleas don’t need much in a host beyond a comfy place to live with adequate nourishment. Felines are excellent hosts for fleas because they are furry and warm, and their fur is often moist, which makes the perfect environment for fleas to live and multiply.

Flea bites irritate cats because they hurt and itch, but scratching can lead to serious infections due to open wounds. Another danger of fleas is that they can carry other diseases that can transfer to the host cat.

The 5 Tips to Help Control Fleas in Feral Cats

Now that you know how dangerous fleas are to cats, let’s consider ways to contribute to the community and help feral cats with fleas. This list will help you get started and hopefully teach you how to assist the numerous feral cats with flea problems.

1. Engage in Trap-Neuter-Return (TNR)

One of the best ways to help feral cats is to engage in TNR, which is a technique for trapping and neutering feral cats and returning them to where they were found. While this technique is highly beneficial to prevent the overpopulation of community cats, you can also use it as a chance to rid those cats of fleas.

This technique will enable you to see if a cat is infested with fleas, which will help you determine which felines need treatment. Also, most cats that are neutered and have adequate shelter and enough food are less likely to have secondary issues from fleas, such as anemia.

2. Put Food & Water Out for Feral Cats

Good nutrition can generally help cats stay strong and boost their immune system. It’s best to give high-quality foods to community cats, but ensure that you provide them in the right amounts to prevent food from lying around. Avoid overfeeding, and don’t leave the food out for more than 30 minutes.

Leaving food outside for extended periods can attract wildlife, which can also carry fleas.

3. Use All-Natural Insecticides

Rather than using harsh commercial products, you can use all-natural insecticides to control the fleas in your area. The two most common are detailed below.

Diatomaceous Earth

This is a fine powder made of tiny algae with hard shells called diatoms. The powder kills fleas on contact, so you can sprinkle it around the shelters of feral cats and in areas where they typically like to hang out.

Beneficial Nematodes

These beneficial worms feed on flea larvae but are entirely safe for cats. You can sprinkle the worms on areas where feral cats like to spend time and let them do their thing.

Nematodes reproduce rapidly and can drastically reduce flea populations in feral cats in just a couple of days. For the most successful results, it might be best to use a lawn sprayer to apply the worms while spraying them on shady, moist areas to promote faster reproduction.

Most nematodes die during cold weather, so you should re-apply them every spring, as that’s when fleas are the most active.

4. Use Standard Flea Medicine

Using flea medicine can control fleas in feral cats, but it is one of the most challenging methods. Standard flea medicine for household cats typically requires handling the feline, which may be tricky.

Still, some versions don’t require engaging with the cat too much. Oral flea medicine can be added to the food that you plan on giving to feral cats. Before using medicine to treat fleas in feral cats, speak to your neighbors to ensure no one else is trying to do the same thing. Otherwise, you may risk treating the same community felines repeatedly.

5. Bathe Feral Kittens With a Flea-Eliminating Shampoo

If you stumble upon feral kittens with fleas, you can help them by giving them a bath with a flea-eliminating shampoo. Kittens are typically much easier to handle than adult feral cats, and you can safely return them to their original location after bathing them.

When bathing kittens, you should create a soapy ring around their neck and anus to prevent the fleas from escaping into the ears and other areas of their bodies. It’s not ideal to try this with adult feral cats since they are typically afraid of people, and such an interaction may traumatize them.


How Can You Know If a Feral Cat Has Fleas?

There are various ways to determine whether a feral cat has fleas. To start, observe how they look and act.

Here are common signs of fleas in feral cats:
  • Itching that leads to excessive scratching
  • Skin scabbing
  • Restlessness
  • Overgrooming
  • Headshaking
  • Hair loss
  • Fleas jumping around the cat’s body

Can Humans Get Fleas From Feral Cats?

Many people fear helping feral cats with their flea problems will transfer fleas to them. However, the chances of a feral cat transmitting a flea-borne disease to people are relatively low.

Also, most feral cats are afraid of people and mainly try to avoid them, so the chances of human-cat contact are generally low.
