Hi! Thanks, sorry, I wasn’t clear… the one I want to switch meds for HAS been tested, he is the one that is MDR1 mutant/normal. He has just never had Sentinel before. From what I can find on the net, Sentinel SHOULD BE safe, but I am just trying to get more input. I think Interceptor is safe for him also. What natural flea treatments do you use? We live in SE Texas, in about the worst flea/parasite area in the county. Thank you for your reply!
