If your cat is suffering, these flea treatments can eradicate the infestation and prevent it spreading to your home. Many get the job done within days or even hours. Be sure to consult your vet first and get the correct dosages, though, because they can cause health issues if misapplied.

Editor's Notes

July 05, 2019:

We can't explain to cats that we're doing something they find annoying — like putting medication on them — for their own good. So, since ensuring their compliance isn't possible, we made sure to round up flea treatments that can be given and administered in a number of ways, depending on just what style of finicky your cat is. Should you worry about Fluffy licking her spot-on treatment away, the Bayer Seresto Collar is a great option. Plus, it's effective for eight months, making it especially helpful for busy pet owners who can't remember to give treatment daily or monthly.

That being said, we did provide some great spot-on treatments like Elanco Animal Health Cheristin and Vectra for Cats. These break the entire life cycle of the flea, from egg to larvae to pupae, making them great long-term preventative options. Should your poor feline be in the middle of an infestation right now, in addition to investing in a quality vacuum to suck up the intruders daily, try an oral medication like PetArmor FastCaps, Novartis Capstar, or Sentry Capguard. These are your best bet since these kill adult fleas the instant they bite your pet.

Special Honors

Comfortis Considering it is the number one recommended flea medication by veterinarians, it isn't surprising that Comfortis is very effective. In controlled laboratory studies, it killed 98% of fleas on cats and 100% on dogs within just four hours. Plus, no matter how many times you bathe your pet, it still works effectively for a full month. You will have to obtain a prescription to purchase it, though. comfortis.com
