Protect your flea-free feline with Sentry Fiproguard! This fast-acting, long-lasting flea and tick treatment contains Fipronil, the same active ingredient as Frontline, to protect kitties from these pesky parasites for 30 days. And don't worry about your little water bug, 'cause Fiproguard is waterproof, so baths won't wash it away. Safe for breeding, pregnant, and lactating cats over 8 weeks old. Keep out of reach of children and give your kitty coverage for a “purrfectly” pest-free life!
