Factors to consider when buying flea control for cats

Before you shop for a flea control treatment for your cat, there are some things to keep in mind. Read on as we explore these factors.


Your cat has soft skin, which is different from other pets such as dogs. Therefore, you need to read the label to be certain that it’s the right product for use. Cats are very sensitive to certain products and can even die when wrong drugs are administered.


Consult a veterinarian

It is important to consider seeking help from a vet before you buy flea control for your pet. He will be able to examine the extent of the infection and also confirm if these parasites are there on her skin or not.

That way, you will not just go and buy any flea control over the counter that may cause more harm than good to your companion. Also, if your cat has another treatment plan in place, your vet doctor will advise you on the best option.

Remember, a wrong application can be fatal; hence it’s important to pay attention to what you give your cat.

Coat size

Depending on the breed, your cat could be having a long or short coat. When it comes to the choice of flea controls, these are made for different coats. When your cat scratches due to flea control, it can lead to hairballs. Cats with long coats would need more applications for the drug to penetrate to the skin.


Every time you buy a product, you need to get value for your money. Before you buy a flea control for your cat, it’s important to read our reviews. Likewise, you can ask friends or neighbors who keep cats.

Some brands may come with appealing and convincing words, but unfortunately, may fail to work on your pet. Although it would be hard to be sure of something you have never tried on your pet before, a small research would go a long way in helping. Fleas can be stubborn; therefore, you need to buy something that works.


You don’t wish to pay through your nose as much as you value your cat so much. That is not to mean you go for low-quality flea control, but good brands are considerably fairy-priced you can choose from.

Side effects

When administering oral flea control, your cat might vomit immediately if she takes it. If that happens, it would be good for you to go back to the vet for him to change and prescribe another treatment that will be gentler upon application.


Check for the age recommendation in the pack of the prescribed product just to be sure it’s the appropriate one for your pet. It would be a huge mistake to give a kitten a drug meant for an adult cat. It can lead to a severe reaction to their skin or even death. On the other hand, it might not be effective to give an adult cat treatment meant for kittens.


Probably you’re asking yourself, when is the best time to buy a flea control for your cat?

There are common signs to look for like excess itching than usual, grooms most of the time, become restless, red patches on the skin, and become irritable.

When this happens, the cat will swallow the flea eggs, and this can lead to worm infestation and overall poor health.

Whether your cat is an indoor or an outdoor cat, flea control is essential. As you search for the best flea control for cats, your selected option should give you value, be safe, and highly effective. We hope that now you can pick the best option out there.
