This seems to work on my under 4kg cat. It doesn't work for tom cat who is big, probably 5+kg, since I've been feeding him. He's part wild so not sure of all his sleeping areas and often has a lot fleas. I've changed to another brand for over 4kg cats, so we'll see if that works! He's in house in day so not having fleas is important. I also find it a little too thick and not easily absorbed into skin quickly. I may give it up completely.
