What are fleas?

If you are an animal lover and have a pet for yourself, then I think you understand better than anyone else. The problem’s fleas – things that make your pet uncomfortable and stressful.

When you were little, did you use to hug your neighbor’s puppies? Surely, after playing with those puppies, you will get itchy, which is the consequence of flea bites. Fleas are not always worth liking, even hearing or seeing them is enough to give us goosebumps. And as a child, the only way you thought you would kill them was to sit and catch them or bathe your pet regularly. 

A flea is a small insect that lives on the body of other creatures like dogs, cats, etc. and sustains life by sucking the blood of those creatures. And of course your cat is also among them.

Contrary to what many people think when they get slim chances of seeing fleas, fleas are not tiny, even we can see them without magnifying glass. An adult flea, is extremely small in size, less than 3 mm long, reddish-brown, which can’t fly but they jump very high

Vomiting in cats

Vomiting is a common phenomenon in cats. In a week, the cat may vomit once or twice to purify the body of impurities, difficult to digest things, and eliminate what is bad for the digestive system. It will be normal if the cat is still active, still eats normally, and has enough mental clarity for the day’s activities. However, vomiting associated with such other phenomena should be considered as anorexia, eating very little or overeating, vomiting several times, lethargy, unconscious sleep, etc.

Do fleas make a cat vomit?

When a flea bites a cat, in addition to the direct signs that a flea causes a cat such as itchy rashes that cause the cat to scratch and cause skin wounds, they are another cause of infectious diseases.

In the process of sucking the blood of cats, fleas eat bacteria that cause disease in cats. What’s especially important is that the bacteria will remain in flea droppings or dirt for more than a week, so contacting between fleas is also the most common source of transmission between cats together.

And of course, if your cat is playful or wandering around, the chances of getting infected are higher than in other cases. Here are 3 infectious illnesses that I would like to recommend to you.


The first one is Bartonella. And as scientists’ research suggests, fleas are the main cause of this disease. And one of the typical signs of this disease is vomiting


The second one is leukopenia, in addition to Bartonella disease, fleas are also one of the causes of leukopenia in cats. In this case, vomiting is also a clear sign


The third one is the plague. As an extremely dangerous infectious disease, the plague spreads rapidly in a short time. Yersinia pestis bacillus, which exists in animals mainly rodents (mainly rats) fleas parasitize on, is the cause. It’s not an exception to your cat either, and vomiting is also one of the noticeable signs

Next is a disease that fleas is an indirect agent of: tapeworm. When fleas annoy the cats, the cats will usually lick and eat the fleas. Unfortunately, fleas contain tapeworm larvae, so when cats eat them, they will be infected with tapeworms. The helminths can cause your cat to vomit by obstructing circulation to the stomach or irritating the stomach lining

Moreover, if fleas consume too much blood from cats, cats will probably be anemic, which usually happens in cats being too old or too young and of course, vomiting is still one of the signs of illness. When infected, infected subjects have a lower number of red blood cells than normal. Red blood cells carry oxygen throughout the body and in insufficient numbers, tissues lack oxygen.

One more thing I think you will rarely notice. If you are not careful with this problem, it will probably have an impact on the health of your cat. If you use flea medication incorrectly, it can cause your cat to be poisoned and lead to vomiting

How to check for fleas in cats

You can use a flea brush to comb from back to front. If torn red rashes appear, the flea result is left for the cat. Also, it is possible to scrape anything from the comb onto the wet washcloth. If it is reddish-brown, it is flea droppings because it is the blood digested. In the event that you are not sure whether your cat has flea bites or not, it is a good idea to take them to the vet to check

How to get rid of fleas from cats

Once you’ve found a cat with fleas, of course, the next thing you need to do is getting rid of fleas by using flea medication

If your cat only has fleas without ticks, use a mixture of pills or tablets is an optimal option. The reason is that they both leave no remains on the cat’s fur and work quickly. You can find them at the vet  

Here I would like to recommend a few medications for you

The first one is Lufenuron (taken orally once a month): This drug comes in tablet or liquid form. The effect is to kill eggs and larvae of fleas

The second one is Nitenpyram (taken according to veterinarian’s instructions): This medicine comes in pill form. The effect is to kill eggs and adult fleas

The third one is Spinosad (taken once a month): This medicine comes in the form of chewable tablets

If you like using topical treatments to treat flea bites, there are a few things to keep in mind

Firstly, you need to hold the bottle upright to prevent it from overflowing and open according to the instructions on the outside of the vial or instruction sheet. Use your hands to scratch the fur on the cat’s neck (just below the skull or between the shoulder blades) to reveal the skin. In this way, your cat won’t be able to lick the medicine when it cleans its fur. Turn the medication upside down and squeeze it all in one spot on the cat’s skin. Make sure the medication is absorbed into the skin, not just on the fur.

In summary, no matter what form of medicine you need, you should read the instructions for using correctly so that it is not mistaken

Take care and love your cat more so that it can live with you for longer.
