Hi I live in NE Pennsylvania and I have a question about heartworms and ferrets that I am hoping someone from Pa. can help me with or anyone for that matter. I just thought if you were from Pa. you would know more about the area. Do I need to worry about our little girls when it comes to heartworms? If so what do I need to give them to prevent this problem? We don't seem to have much of a mesquito problem here no breeding grounds for them and we didn't have a problem last year. I would appreciate any help anyone on the FML could give me. Thanks, Diane,wiggles, cocoa and daddy too!!! [Posted in FML issue 3026]
