and if not for the fact that last month Ziba licked some and went through the frothing mouth stuff, I have had no problems. But now Ziba remembers the smell of the stuff and this time gave me the stink eye for two days, until it all sank in and she could not smell it...gotta say when I combed her, what came off were 2 fleas on their deathbed...not many on the floor now and she is beginning to use the floor to get around again...Mira still hops around, but that will change.
