I haven't tried Frontline, mostly because I have questions about it. Doesn't it work for an extended period of time (at least from what I remember about treating a cat)? It seems like it must be systemic, in which case why couldn't traces of the chemical get into the egg? What is the chemical, anyway? Is it used in humans at all?
I haven't actually checked for mites in a while, but today I discovered worms on the poop board. I'm going to treat with Valbazen, but I may wait another month or so. I read that it is stressful to treat for worms and you shouldn't do it while they are molting. A bunch of mine are molting now. It seems like someone will always be molting though, so I'm not sure how long I will wait.
