Just wanted to let everyone know that whatever you use on your furbaby, be sure and watch them very closely. I have an 8 month old, LuLu, and my best friend bought her sister, Miss Priss. My friend tried Comfortis with her little one and ended up in the emergency vet hospital. I mentioned it to our vet and he told me not to ever try it on LuLu since one of her siblings had a reaction to it. So.....just be careful.. But....just to join in....I, also, am having problems with FLEAS. I have 3 inside babies and I bathe them at least once weekly. I have tried Frontline, I do bathe my in Dawn, I just follow it up with conditioner and then I spray with Adams Flea & Tick spray. I am praying this "epidemic" is over soon. It is so annoying.
