Do cats get mosquito bites? We all get annoyed by mosquitoes. We have to fight mosquito bites and their consequences. But, do mosquitoes go after cats? What are the effects of mosquito bites on cats?

Cats can get mosquito bites the same way humans do. Cats are covered in fur; therefore, mosquitoes tend to attack mainly cat’s noses and ears. The main danger for cats is not the bite in itself. It is the viruses and diseases that mosquitoes can transmit.

Let’s see what are the facts.

Do cats get mosquito bites?


Cats are luckier than humans when it comes to mosquitoes. They are covered in fur, which is a layer of protection against mosquitos. Mosquitos have to fight hard to bite them. However, if you ever dealt with mosquitos, you know that they can find the only piece of uncovered skin and bite it.

Mosquitos can attack a cat’s nose and ears since they are not covered with fur. There are some cats breed that does not have fur. Those breeds are entirely exposed to mosquito bites.

Therefore, yes, cats do gets mosquito bites. In some cases, the problem is not only the fact that a mosquito bite itch, but the viruses and diseases mosquitos carry with them. It is important to prevent mosquitos from entering the house and protect your cat from mosquito bites.


Mosquitos are famous insects because they are known to be vectors to many diseases. A mosquito is any member of a group of about 3,500 species of small insects belonging to the order Diptera (flies).

The mosquito’s saliva is transferred to the host during the bite and can cause an itchy rash. Besides, many species can ingest pathogens while biting and transmit them to future hosts. In this way, mosquitoes are important vectors of malaria, yellow fever, Chikungunya, West Nile, dengue fever, filariasis, Zika, and other arboviruses.

Therefore mosquitos can be dangerous for cats and humans. But cats can get worms from mosquitos. Mosquitos can bite infected animals and carry the worm’s eggs to the next victim.

The type of worm that is transferred by mosquitos to cats is the heartworms. This type of worms gets to the heart and lungs, causing severe illnesses and sometimes death.

A mosquito bites an animal infected with heartworms. In the contaminated animal’s bloodstream, there are baby worms produced by heartworms already developed in the animal body.

When the mosquito bites that animal, picks up the baby worms, they are microscopical. The mosquito carries those baby worms around. The baby worm takes 14 days to mature to the point of becoming infectious.

At this point, it can be transferred to a new host with a new mosquito bite. The bite opens the skin and permits the baby worm to enter the bloodstream of the poor victim. It is gross. From here, the worm can take six months to grow up to a full size. (with males reaching about 4 to 6 inches in length and females getting about 10 to 12 inches in length)


The most common clinical signs of heartworms infection include:

  • Intermittent vomiting (sometimes of blood as well as of food)
  • Diarrhea;
  • Rapid and difficult breathing
  • Coughing and gagging
  • Loss of appetite
  • Lethargy
  • Weight loss
  • Distended stomach or belly due to the fluids in it

Unfortunately, heartworms are dangerous, and one could see the symptoms too late when the cat is already collapsing. Cats can display the symptoms listed above, but cats can faint and die in the most extreme cases.

In some cases, the heartworm symptoms can be mistaken for other illnesses and, therefore, never found until it is too late. The best course of prevention is to keep away mosquitos and routinely deworm cats.
