Quick answer: Bravecto Topical Solution for Cats contains fluralaner and is a prescription spot-on that kills fleas and certain ticks for up to 12 weeks with one application. It does not prevent heartworm or treat intestinal worms. Bravecto Plus for Cats adds moxidectin for heartworm prevention and some worms, lasting about 2 months. Other options include monthly combination products. Your vet can recommend the best fit for your cat’s lifestyle and health.
What it covers
- Fleas, for up to 12 weeks
- Certain ticks, with protection times that vary by tick species (check the label)
- Not heartworm, ear mites, or intestinal worms (Bravecto Plus covers some of these)
Safety considerations
- Prescription only. Use the correct weight-range product and follow label age and weight minimums
- Fluralaner is an isoxazoline. The FDA has noted these products can be associated with neurological reactions such as tremors or seizures in some animals. Tell your vet if your cat has a history of seizures
- Common side effects can include vomiting, hair loss, or itching at the application site
- Never use dog flea products on cats
Alternatives to discuss with your vet
- Bravecto Plus for Cats: adds heartworm prevention and some intestinal worm coverage
- Monthly combination topicals that cover fleas, ticks, heartworm, ear mites, and some worms (such as Revolution Plus)
- Other monthly flea-only or flea-and-tick products
How to choose
- Does your cat go outdoors or live with dogs that go outdoors?
- Is heartworm a risk in your area? (Cats can get heartworm even indoors)
- Would a 12-week or monthly schedule be easier to keep up with?
- Any history of seizures or skin sensitivity?
