And this is why at work we never recommend or advise clients to use OTC pyretherin based flea products. We've just seen way too many bad reactions, and sick pets because of them.

The rub is that many companies will advertise them as 'natural' just to sucker people into buying them.

Have they all forgotten the big Hartz recalls a while back when it was killing cats? And at that all the company did was re-label the product, they didn't change a thing in it. *sigh*
