Consistent, proactive care is the best flea treatment for cats.

For routine flea preventive care, you may or may not need a prescription from your veterinarian. There are many effective brands of over-the-counter flea medicine and treatments for dogs and cats that do a good job of stopping infestations and preventing new ones. For particularly effective flea treatment for cats, look for a medication that kills fleas at various stages of the flea life cycle, from eggs to larvae to adult fleas. This will ensure that existing fleas are eliminated and that eggs and larvae never have a chance to reproduce. Many of the best-selling flea treatments for cats can be purchased without a prescription.

Your veterinarian will likely recommend flea medicine based on a number of factors, including your cat’s age, weight, sensitivities and lifestyle—as well as whether a flea infestation already exists and, if so, how severe it is. If you need help differentiating among the various treatments available, check out Petco’s guidance on 6 Flea Treatment Options for Your Cat. Typically, vet recommended flea treatments for cats include medications that kill fleas at multiple life stages, from eggs to adult fleas. And your vet might recommend a medicine that also battles ticks and lice so that your cat is armed against multiple types of parasites at once.
