Buying Guide for Flea Treatments

When determining the right flea treatment for your cat, it is important to consider several factors to ensure you get the best product for your needs. Fleas are harmful bugs that can cause dermatitis and other itching issues for your cat. They can also carry a variety of diseases.

These fleas do not just affect your cats, they can bite you and other household members too. It is important to completely eradicate the fleas from your pet and your home to maintain safety and comfort. Understanding the flea provides the first step to identifying the right type of flea treatment.

Flea Life Cycle

An adult flea feeds on blood from its host. If an adult flea cannot find a host, it will die within 12 hours. Many flea repellents can help prevent adult fleas from feeding. However, the different stages of a flea’s life cycle are not killed by these methods.

An adult female flea can lay 50 eggs each day. It can take anywhere from two days to two weeks for an egg to hatch when conditions are right. From the larval stage to the pupal stage, fleas do not need to feed. This period can last a few days up to a year. Once the flea finds a prime host, it will feed to begin laying eggs and begin the life cycle over again.

Why is the Life Cycle Important?

It is important to understand the life cycle of the flea to identify the right treatment to completely remove these pests from your pet and your home. Some pet treatments only target the adult fleas. Sometimes, this is only after they have fed on your cat. Once a female flea feeds, she can lay eggs.

If the treatment does not target the eggs or other stages of the flea life cycle, the infestation can begin again when the treatment wears off. This can force you to have to re-treat your pet every couple of weeks. A treatment option that targets the entire cycle can eliminate the fleas completely.

What Kind of Cat do you Have?

Considering your cat is very important when picking a flea treatment. If your cat is an outdoor cat, you will want to find something that prevents fleas from attacking them in the first place. Outdoor cats are very susceptible to fleas and constant protection is necessary. Indoor cats, however, are still susceptible to fleas, but may only require treatment as necessary.

The age and weight of your cat is also an important factor to consider. Many flea treatments are for specific ages and weights. Giving the wrong medication can be hazardous or ineffective for your cat. Always weigh your cat and check the labeling instructions before using any treatment.

The health of your cat. Some cats are prone to allergies or have health issues that may cause adverse reactions when using some products. If your cat has any health issue or concern, speak with your veterinarian before using any flea treatment.

Do Not Use Dog Treatments

Cats are very different than dogs. They also require different levels of medications than dogs, even of the same weight. Using the wrong medication for your cat can have serious effects on their health. Even products that are the same medications as the cat version, may not have proper dosing guidelines for a cat.

There are some dog flea treatments that contain additional medications that can kill cats. It is vitally important for the health of your beloved cat to always read the labels and dosage information before giving any flea treatment to your pet.

Take Care with Topical Treatments for Cats

Topical flea treatments for cats should be applied to the skin at the back of the neck, right at the base of the skull. It is important that you follow these directions for application. This area prevents the cat from licking the medication. Although safe on the skin, these treatments can be harmful if swallowed by your cat.

It is also a good idea to keep other pets and small children away from the cat after treatment. The treatments can take up to a day to completely dry or absorb into their skin. Read the labeling instructions on the treatment for an accurate time-period to prevent the medication from being transferred and causing harm.

Talk with Your Veterinarian

It is always a good idea to speak with your veterinarian before starting any medication or treatment for your pet. They can offer the best advice tailored to your specific situation and your pet’s needs. However, in most situations, these treatments are safe and effective for cats without health issues or allergies.

However, if your cat does have any concerning allergy or health issue, do not give them any type of treatment until speaking with your veterinarian. Any questions or concerns about safety, the effectiveness of the products, or recommendations, your veterinarian is always the best source of information.
