To Ed Swartz, I have had great success with Brewer's Yeast and Garlic. Several years ago, I had a terrible flea problem. Since I am allergic to fleas, it was something I needed to get under control. I was going crazy - flea bites the size half dollars. I treated my house with Duratrol premise spray and started giving my dogs BY tablets. I have 2 dogs, 3 cats, 17 ferrets, and NO FLEAS!! In fact, I haven't had fleas since, and since my allergy makes me so sensitive, I'm the first to know if fleas are in the house! Another interesting story about BY. My very first ferret, Mickey, acquired in '85, developed a horrible skin condition. 3 different vets scraped it, looked at it under the scope, and couldn't believe it was Demodectic (spell??) mange. Nothing I tried work: antibiotics, tar dips (I refused to do a Mitaban dip which was suggested several times, but after reading the labe no way was I going to dip my ferret in that poison), Goodwinol ointment. Poor Mickey, he developed a crust around his front toes and around his mouth. I had to scrub it off everyday with a tooth brush (he could have developed foot rot) and put salve on it. This went on for months and no one could help me. At the time, not really knowing ferret people, I tried the vets out in Wyoming (Black-footed Ferrets), who suggested trying Vit B12 injections. That didn't work. Then Mickey developed insulinoma; I had read in UFO that BY in chicken baby food helped control insulinoma. So I gave Mickey 1/8 tsp of BY in CBF everyday - and guess what??!! Within 3 weeks his mange cleared up and he was never bothered with it again!!@!! BY has B vitamins in it - the injections we used were weekly; it's possible that the daily dose worked better. But I am a true believer in BY. My vet says it works by making the animal taste unappealing to fleas - he says sometimes it works, sometimes it doesn't. It won't hurt the animal though, and it's worth a shot. I've had great success with it. BG, I know this is long, hope you don't have to cut any of it!
