My ferret, Zeus, sometimes coughs alot. I have changed several things that I think may have helped his coughing, it has slowed down. I now wash all all linens and clothes in dye and fragrance free detergant. I had switched from regular kitty litter to Yesterdays news and Fragrance free natural litter. I have noticed him much less coughing. I was wondering if I at times should give him Benedryl? If so......when and how much? Also...the liquid kind? Any suggestions? Tam [Posted in FML issue 4787]
