It's been effective for 30 days straight,so I don't have to worry about reapplying every week.

The treatment is safe for indoor and outdoor use, so whether we're staying home or exploring the neighborhood, my cat stays protected.

I've used it for months now and haven't seen any side effects, though I always check the label before use to be thorough.
Even though it's not suitable for kittens under 8 weeks or cats under 9 lbs, the product's ease of use and reliability make it a win for larger cats. The subscription option is a lifesaver, ensuring I never miss a dose and always have a supply on hand. It's a bit pricier then some alternatives, but the peace of mind it offers is worth it.
