Pet's info: Cat | American Shorthair | Male | neutered | 1 year and 3 months old
My cat has fleas. I used the seresto collar, which worked well for about 3 months but the fleas slowly came back. After that I tried sentry shampoo which didn't work at all. After that I tried sentry spot on once last week and once this week, which also didn't work at all. Is the best bet to get another seresto collar? I didn't know if him getting fleas meant that the fleas are no longer affected, or that the collar just got worn out. Thank you!
