(2 pack) Advantage II Vet-Recommended Flea Prevention for Large Cats 9 lbs+, 4-Monthly Treatments

I love the way this product takes care of my big boy! He knows when it is time for more, and he will stay in for a day because he cannot go out and get wet for 24 hrs after. He does it on his own. He is probably the smartest cat I have ever had, and I have had several for many years. I spent a lot of money on various flea remedies, and none worked on him. Advantage was great for some of my other animals, so I tried this one because my kitty is a big boy. It WORKS! No fleas, finally, after putting him through all those other sprays, pills, etc. So, I still need a tick killer cuz when I used this product, it was not enough! He is a 2 yr old that goes out and in every day. I got a tick collar, and he does well now without all the bugs. There is no smell either. The little vial that comes with the medication inside is REAL easy to apply. It is so easy to use; I love it. Just open the package, get the vial and put it on the cat's neck after pulling fur back. It may tickle the kitty for a minute or so. Also, it is normal that some liquid drains into the fur, but no worries.
