My cat has fleas, Advantage II failed. How to rid cat and house?

Updated On September 23rd, 2025

Pet's info: Cat | American Shorthair | Male | neutered | 11 years and 3 months old | 14 lbs

I have an 11 year old outdoor/indoor cat. When my father died last year, my cat decided he wanted to live outside for some reason. Since then, he has a heavy flea problem. For the past 4 months, I have been applying Advantage II but it appears to do nothing. What is the best flea items I can utilize to rid the cat and house of fleas? He does not argue with a warm water bath outside but winter is coming and he needs a real bath with flea shampoo. What do you recommend we do? Thanks.

Get a capstar tablet and give it to Midnight. This will kill every flea that is present on him within 30 minutes. Then I suggest you change flea prevention. I would recomend you get Bravecto for cats from your vet, it is expensiven, but it lasts up to 4 months preventing ectoparasites (ticks, fleas and mites).
