Hi all, I just wanted to ask everyone... 1) What do you do for Heartworm Prevenative? I do animal rescue and we get in a lot of dogs with Heartworms and living out here in cattle land there are a high case of moquitoes. 2) I was reading this morning that you can use flea preventatives on ferrets like Advantige. What do you all use? I do bathe my ferrets in a flea and tick shampoo for ferrets. Thanks, Tina & the Critters [Posted in FML issue 3297]
