PetArmor Plus Flea and Tick Prevention for Cats, Cat Flea and Tick Treatment, 3 Doses, Waterproof Topical, Fast Acting, Cats Over 1.5 lbs

I put this on both of my cats about a week ago. Per the box, it says it starts to work 24-48 hours after application. I bought a flea comb and just checked… there are still a lot of live fleas on them. They are inside cats and not sure why it hasn’t started to work.

Giving 3 stars bc my cat had a bad reaction to it, he's super sensitive in the spot we put it and won't let us touch him there now, 4 days later now and we still can't touch him there... I can't say if it works or not and i won't be using it anymore obviously my cat is sensitive to it so I'll have to go back to previous brands that use different ingredients (none of the previous brands I've used have this brands ingredients and the other brands didn't cause this reaction, but they also don't prevent tics like this one)

Love how fast this hits and how easy it is to apply. It stays effective for a long time and is simple to use on my cat over 1.5 lbs. If you want quick action that lasts, this is a solid pick.

This does the job of killing flea eggs and larvae quickly. I also trust the formula since it's from PETARMOR. The waterproof feature is a plus, making application easier. However, I wish it used more natural ingredients and had more doses per package. The drying time could also be faster to make the process less messy.

It works on my fat cat
