Which is the best flea and tick medication for cats? A veterinarian explains in detail.

This year, due to the mild winter, there are days in March when it's warm enough to sweat.

When spring arrives, external parasites such as fleas and ticks reproduce, making it a troublesome season for cats. Those who own cats may have received notifications about flea and tick preventatives from their veterinarians.

So, what kind of flea and tick preventative should you choose? We will explain flea and tick preventatives in detail.

The Necessity of Flea and Tick Control for Cats

In fact, many cat owners have never performed flea and tick control. The reason for this is that they believe fleas and ticks won't infest their cats if they are kept strictly indoors. However, just because a cat doesn't go outside doesn't mean it won't get fleas or ticks.

Fleas and ticks typically live in grassy areas and become active and reproduce when the average temperature reaches 13-14°C. They then jump onto approaching animals and feed on their blood. If a pet owner walks near grassy areas, there is a risk that fleas and ticks can attach to their clothes or bags and be brought indoors. Once inside, they can reproduce because of the stable indoor temperature.

At the author's veterinary clinic, there have been cases of severe flea infestations in strictly indoor cats, caused by owners bringing them in from outdoors.

Fleas and ticks are not only a problem themselves, but they also transmit various pathogens. Some diseases transmitted by fleas and ticks can also infect humans. Furthermore, many of these diseases can be life-threatening.

The following are examples of diseases caused by fleas and ticks:

• Allergic dermatitis (fleas/ticks)
• Dipylidiasis (fleas)
• Hemobartonellosis (ticks)
• Lyme disease (ticks)
• Severe Fever with Thrombocytopenia Syndrome (SFTS) (ticks)
• Anemia (fleas/ticks)

Using preventive medication for fleas and ticks can prevent infestation, and consequently, prevent the diseases listed above. Therefore, even strictly indoor cats require regular flea and tick control.

Types of Flea and Tick Preventatives for Cats

There are various types of flea and tick preventatives, from over-the-counter medications available at pharmacies and drugstores to veterinary medicines only available at animal hospitals. There are also various forms, such as collars, shampoos, and spot-ons.

Flea Collars

These are available over-the-counter and are not expensive, but they are not effective against ticks. Also, they can cause hair loss or dermatitis at the application site. They have no preventive effect unless replaced regularly.

Shampoos

There are also shampoos for flea and tick control. The advantage is that you can wash your cat immediately when you notice them and they are inexpensive. However, cats generally don't like baths, so frequent bathing can cause stress, and relying solely on shampoo for eradication is not a good strategy.

Over-the-Counter Spot-On Treatments

Spot-on treatments are liquid preventatives applied to the base of the neck. The price is also not very high. Since owners apply them themselves, they may not be applied correctly, leading to ineffective eradication. In recent years, drug resistance in fleas and ticks has emerged, and over-the-counter medications may not be effective. Reports of toxicity have also surfaced.

Veterinary Spot-On Treatments

The spot-on treatments available at veterinary hospitals include various types that are effective not only against fleas and ticks but also lice, and can even deworm and treat ear mites.

Furthermore, heartworm disease, famous as a dog disease, also affects cats, and even a few parasites can cause severe symptoms. Veterinary medications even include preventatives for heartworm.

Some treatments are administered once a month, while others are every three months. Since they are applied at the veterinary hospital, they are administered accurately. Regarding drug resistance, there are also new preventive medications that use different drugs to combat it. However, the price is higher compared to over-the-counter medications, and it can be stressful for cats that dislike visiting the vet.

Which Type of Flea and Tick Preventative is Best for Cats?

From a veterinarian's perspective, I believe that veterinary-exclusive medications are indeed the best.

Pharmaceutical companies develop these medications based on solid data regarding preventive effects, drug resistance, and reports of toxicity. Additionally, veterinarians select the appropriate medication based on the owner's needs and the cat's condition.

Since the veterinarian selects a reliable eradication method and administers it accurately, it saves the owner trouble. If you are unsure which medication is best, it is a good idea to consult your veterinarian.

Administering the preventative at the vet ensures reliable prevention, and sometimes a simple health check or nail trim can be done at the same time. Regular check-ups can also lead to early detection of diseases.

For owners, it allows them to feel more comfortable with the vet and find a primary veterinarian they can easily consult. For these reasons, choosing veterinary-exclusive preventatives is a good idea.

Summary

There are various types of flea and tick preventatives and places to purchase them. Even for indoor cats, it is important to perform regular control as owners can sometimes bring parasites indoors.

If you find fleas or ticks on your cat, do not panic and try to crush or forcibly remove them. Doing so may push pathogens from inside the flea or tick into the cat's body, or leave parts of the parasite's mouth embedded. Instead, consult a veterinarian immediately.
