Ovitrol XTend Flea Tick Spot On for Small Cats (2.55 lbs) 3 Month

My adult cat seemed a bit lethargic the first day I put it on him, but I see no fleas under his neck where they were before. He's fine today, and with no visible fleas. This is the first month I've used it so I will update my review in the coming months. I think he's bigger than 5 pounds but I got the small cat anyway, because I didn't want to overdo it the first time I used it. The applicator is awesome. I gave it 4 stars only because I don't have long-term experience with it yet.

Must apply directly to skin to be most effective.

Cats are still infested with fleas. Scratching a bit less, but flea comb pulls many fleas from their fur.
