Buyer’s Guide: Selecting The Best Flea Treatment for Cats
Veterinarian Recommendation: Because there are so many flea treatments on the market and most of them involve chemicals, it is important to discuss flea treatment directly with your cat’s veterinarian. They are professionals that are well versed in treating fleas and will be able to guide you on the best path to keeping your cat and home free of fleas.
Cat’s Age: As seen above, most flea medications are designed for kittens that are at least 8 weeks of age and with some brands, much older than that. You do have to take into consideration the age of the cat you are providing treatment for and ensure they are getting an age-appropriate medication. Very young kittens are typically treated with bathing and flea comb until they are of age to tolerate flea prevention.
Cat’s Weight: Before purchasing a flea treatment for your cat, you need to know its exact weight. Flea treatments are designed for different weight ranges and it is very important to administer the medication for their proper weight range.
Cat’s Health: Discuss the current state of your cat’s health with your veterinarian to help you come to the best choice of flea treatment. A licensed veterinarian will be able to recommend the best option for your cat’s overall health. Keep in mind that cats with sensitive skin may not tolerate topical solutions and it may be best to go for an oral medication.
Type of Parasite Protection: Some of the flea treatments on the market can prevent and treat other parasites such as ticks, roundworms, hookworms, eat mites, and even heartworms. Having extra protection is always a plus but not all treatments will be effective against additional parasites. Also, make sure to read the product information to see if the product can help kill the flea lifecycle by killing eggs and larvae. Some treatments are only effective against adult fleas and with more severe infestations, you may need something that can handle all lifecycles.
Preference: You need to consider which option would be the best for you and your household. For instance, flea collars do not need to be touched by small children, and topical solutions can be messier and have the risk of being licked off by other animals in the household during grooming. Only you know what your household consists of and the habits of the people and animals within the home. Again, your veterinarian can help you make the best decision for your circumstances.

Efficacy Issues in Products
It is important to keep in mind that efficacy issues can occur when attempting to treat a flea infestation. Killing the adult fleas is easy, but eliminating the larvae, eggs, and breaking the life cycle can be challenging.
- Topical Medication
- Oral Medication
- Collars
- Shampoos
- Powders
- Sprays
- Flea Dip
Fleas can be resistant to some more widely used products, so it is not unusual to run into a product that simply does not work for your cat. Other times, you may notice a product does not work for the length of time advertised. For example, a once per month medication may only keep the fleas away for two weeks.
It is very important to discuss flea treatment and prevention directly with your cat’s veterinarian so that they can give you the best option in tackling this pesky problem.
Eliminating an Infestation
To eliminate a flea infestation, not only will your cat need to be treated, but any other animals in the home that can fall victim to fleas such as other cats, and dogs. You will also need to treat your home, which can be the most difficult part of the process.
Flea eggs can hide in the carpets, furniture, and all over the house. When the adult fleas are killed off, their eggs are still able to hatch, and the issue begins all over again. You need to eliminate the entire lifecycle of this parasite for successful elimination and a flea-free home.
It can take up to 3 months to fully rid a home of an infestation and in some cases, you may have to bring in a professional to take care of the job. More than one treatment of the home may be necessary.
Speak to your veterinarian and they will be able to help guide you through the process and ensure your pets are covered on the treatment end.
Possible Side Effects
Treating an animal for fleas involves chemicals and side effects are possible. While these treatments are heavily studied before being released for use in our domesticated pets, reactions can vary from individual to individual.
Ensure other animals in the household are prevented from licking off any topical flea solution on another, as this can be dangerous. Make sure to read any labels on any treatments being done in the home to ensure all members of the household, both human and the animal will be safe during the process.
Be sure to discuss any possible side effects of the flea mediation with your veterinarian. You will need to ensure the medication is well-tolerated and keep an eye out for any symptoms of toxicity.
Conclusion
Bravecto Topical Solution is a great overall choice, though it does require a prescription and is for use in cats 6 months or older, it gets the job done well and kills fleas, eggs, larvae, and ticks with an efficacy of up to 12 weeks.
Frontline Plus for Cats is a great choice if you are looking to get good value at a lower price. Frontline Plus is available without prescription and easy to obtain.
Revolution Plus is a great choice for a topical solution that is effective against fleas, ticks, heartworms, ear mites, roundworms, and hookworms. It dries quickly and is easy to apply.
