II for Cats Over 9 lbs (LG), 4 MOS/Box

Vet recommended and works great

Kills fleas as good as the expensive kind.

The price is right, so I had to try these. My only complaint is the difficulty I had in opening them. I am sure it has something to do with safety, but I have seen versions that are easier to open. I was able to see NO fleas in my cats within a week. People forget that unless you are shampooing or brushing those fleas out? Treatments can take a bit of time to work. Another trick with these specific types of products is technique. You can't just squirt this into one spot and rub it into the hair. This one has the same ingredients as some of the more expensive brands. It WILL work exactly the same. But as with ALL of them, you must apply them correctly. I make sure to apply on the actual skin on the small area behind their neck that they cannot reach. But I also pick at least 3 separate spots in this area. Use a comb or just your finger to part the fur until you see skin. Apply directly on the parted skin area. On top of making sure you get it on the skin, I also use the tip of the applicator to kind of rub it in. Again- not into the fur, but into the skin. I know some that will pick even more than three spots. They will continue to part the hair and dab onto the skin until all the fluid is used. Then it is important to let everyone know- NOT to pet the cat in that area for the next several days. Let it do its thing.

Had a terrible flea infestation..1 of my cats got out. Everything I bought didn't kill them. My friend who works for a veterinarian told me about these she was right so much cheaper than 40 dollar and they worked quick. I've bought them twice now. Still happy! No more fleas! These are the best and believe me I tried them all on my cats and brothers dogs. In twxas we had a horrible flea infestation due to drought and not enough winter last yr to kill the bugs. Fleas where everywhere. As always I treat my yard as did my brother but we still had fleas in our furry friends. In the future this is all I'll buy. The Amazon basics are ok. I used as a follow up due to iut if stixk in these and they seemed to work well also! Good luck with ridding the pest on your furry friend and this will keep them away. Apply high on neck because they will kick ut off and you'll think product didn't work lol nope they are sneaky so kinda watch your pet for 24 hours so they don't kick off medication and it gas rime to sink in and work! Good luck

Read a lot of reviews for this product and it was a mixed bag. Did not work for any of my 4 cats! Switched back to Amazon basics for the topical flea treatment for my cats!
