The carrier is supposed to be different - meaning it may not be as waterproof, may not last as long, and may not distribute over the pets body as well. This is just the info we got at the vet clinic I work at - not sure if it's true or not. I'll wait to see what others think before I try.
We just did the 2nd application of the stuff on our Aussie and the cat and so far so good. We are living on 17 acres of woods so ticks are all over the place out here. They're not too bad up in our little clearing as we let the chickens and guineas free range all day but hit the woods further back and forget it, they eat you alive. What we also like about it is the fact that there's no nasty smell to it, at all. I dreaded doing the cat as she's a psycotic little thing and I dosed her when she was eating and I came away without loosing any blood! Hope this is some help! Dawn
