My indoor cat has fleas from outside cats. What's the best solution?

Pet's info: Cat | Domestic Longhair | Male | neutered | 25 lbs

None of the current products completely rid my indoor 25 pound cat of fleas. The fleas must come from outside cats fed by the other apt. dweller. What can I do? Thank you. BOB KENT

The majority of flea problem (80%) is due to the environment. You can try to treat your yard and your house and continue to treat Tippie as the medicine will help break the life cycle and provide some relief. I do not know which products you have tried, but Bravecto is a good as one application can last for 3 months. You may want to look into a Seresto collar also as this can last 6-8 months for prevention. No flea products do well for repelling fleas, so despite having medication on them, fleas will still have to get on him in order to ingest the medicine to be killed. So seeing fleas does not mean it is not working, just means he is still finding them in the environment.
