Amazon.comBiting fleas are more than just a nuisance for your cat. Left unchecked, they can cause serious disorders such as flea allergy dermatitis, secondary skin infections, tapeworms, and even anemia. This topical flea treatment stops fleas before they become a problem. Providing a full month of protection, it begins working in minutes, killing 98-100% of the fleas on cats within 12 hours, and 99% of flea larvae within 20 minutes. Plus, since dead fleas can't lay eggs and dead larvae can't hatch, the flea's life cycle is halted. Any new fleas your cat encounters are killed within two hours--preventing re-infestation for as long as four weeks.
