What happens when cats eat flies?

Cats are carnivores and so they need to eat meat. Flies are usually the only insect that cats eat because they are easy to catch and provide a lot of protein.

Cats can catch flies when they fly close to their mouths. This can happen while cats are eating or hunting around a trash can for scraps of food.

Cats are obligate carnivores, meaning that they need to get their protein from meat. Flies are a great source of protein for cats because they have a high protein content.

Some cats eat flies because they like their taste. As gross as it may sound to humans, flies are often sweet and tasty to cats.

Cats have a high metabolism, so they need more food than dogs to keep their energy levels up. This is why they eat everything from birds to mice and even insects like flies.

It’s important to note that even though the pesticide on the fly is a few days old, it can still be toxic.

You can read more on insecticide toxicity in cats here.

  • Flies are bacteria carriers (harmful/pathogen transmissions)

Let’s not forget that flies love to feed on feces and decaying matter. While the bugs go about enjoying their feast, they tend to pick up some dangerous pathogens.

Now, imagine if by bad luck your fur baby happens to eat a contaminated one. Most likely your poor baby will get infected.

  • Diarrhea and vomiting ( eating excessive flies).

Cats have a natural instinct to hunt and eat flies, which makes them susceptible to getting sick from doing so.

Here are some of the things your cat may pick after eating a fly:

Bacterial poisoning

House flies can easily pick up some bacteria from their surroundings and transmit the pathogens to your cat.

Treatment:

  • In cases of diarrhea, make sure to keep your cat hydrated.
  • Consult a vet to get some antibiotics for the infections.
  • Maintain high levels of hygiene and aim for a fly-free home.

Myiasis

According to the MSD Vet Manual, this is also called fly strike or maggot infestation. Happens when a cat eats infected fly eggs or when a fly lays eggs on a cat’s wounds.

Pseudomiasis occurs when a cat feeds on maggots.

Cats with long matted coats are high candidates for myiasis. This is because the long fur will most likely have some excrement which then creates a perfect breeding ground.

Treatment:

  • Treat any open wound on your cat. Consult your vet on this.
  • Trim any fur around the wound.
  • Aim to have a fly-free home to deal with transmission.
  • Routinely groom your cat especially if your fluffball has a long coat that gets matted easily.

Allergy

Allergies in cats occur when the feline’s immune system overreacts to something from the flies. It then ends up trying to remove the foreign bodies (allergens) and cause an allergic reaction.

Here is a table summarising sickness and symptoms of illnesses from flies:

SicknessSymptoms
Myiasis
(Maggot infestation)
– Lesions in ears, nose, anus & private parts, eyes, and neglected wounds.
– Maggots in the lesions.
Bacterial poisoning – Diarrhea
– Eye infections
Allergy– Rapid swelling in parts of the body.
– Difficulties in breathing.
