Yes, please have some of ours! Sienna is a flea magnet. It doesn't help that all the cats are on Advantage, but her fur is so thick the Advantage just disappears. So of course, she gets all of the fleas that aren't going on the cats. I just tried the Comfortis pill, and it seems to be working great! I, too, hate using chemicals but in this case it's better than suffering with fleas.
I tried DE on Sienna, but it was he** on her coat. It's very drying, and I wouldn't reccommend it for long- or double-coated dogs. It works pretty well on the kitten, who is almost old enough for Advantage.
I'm also noticing that the fleas gravitate towards the poor white kitten and not so much on the darker cats. Or maybe they're just more obvious in contrast to light colored fur?
