Hello, my name is Dr. Shines and I am happy to help. Ugh! Fleas are the worst but the good news is that you can effectively get rid of them if you use a good product and are diligent in the treatment. Here is a link about the flea life cycle: https://vcahospitals.com/know-your-pet/flea-control-in-dogs The flea life cycle can last as long as 6 months. The key to getting rid of fleas is to make sure EVERY dog and cat in the house is treated with a good flea prevention AND that this treatment lasts an entire 6 months. Your vet can give you access to the best flea products on the market. top products for cats are Revolution and Cheristan. I recommend to ask your veterinarian what they used and to continue it for a solid 6 months. Also know you will likely continue to see fleas for at least 6 weeks (assuming your product is working correctly) because of the newly emerging adult fleas. Lastly, know there is great variation in the effectiveness of topical flea products. As far as they go, for over the counter options, name brand Frontline and Advantage are your best options (but what you get from the vet is usually newer and better). I hope this helps and please feel free to reach out with any additional questions.
