TevraPet

TevraPet Actispot II Flea Treatment for Large Cats 9+ lbs | 6 Doses | Powerful Prevention and Control

POWERFUL FLEA KILLING TREATMENT FOR LARGE CATS: TevraPet Actispot II is a waterproof topical for cats that kills fleas, flea eggs, and flea larvae for up to 30 days after each application
VET APPROVED FORMULA: TevraPet Actispot II uses Imidacloprid and Pyriproxyfen - the same safe and effective active ingredients found in Advantage II - but costs far less. Every cat deserves veterinarian quality treatment, Actispot II helps you provide the same level of care without breaking the bank
FAST ACTING AND LONG-LASTING WITH NO BITING REQUIRED: TevraPet Actispot II REPELS and KILLS fleas on contact, without your cat being exposed to bites. Begins killing within 24 hours of application, and starts repelling immediately.

Actispot II safely kills flea eggs and larvae to prevent re-infestation so your cat can get on with napping in the sun and strolling (or stalking!) through the garden
EASY-TO-USE, MADE IN AMERICA: We proudly make every dose of Actispot II here in the USA and rigorously test for quality and potency. Each package comes with six (6) easy to apply, fully waterproof topical applications that ensure your friend has safe and reliable flea protection and control for up to six (6) months
