I would mate, honestly it really is good stuff espeacially if theres alot of small ones. If you've got them registered at the vet's just give them a call and they should give you some,
I say this because I could'nt get it over the counter.
Just massage it in there fur with rubber gloves and they'll all have dropped off by the next morning
