Suki, Please don't take this as a personal attack on you as it is not. Have YOU ever seen anaphylactic shock in a ferret?? Well I have, 3 times with 3 of my ferrets that received their Fervac Distemper booster shots.( One was from a breeder and the other two were from pet shops.) One was a year old and the other two were 2yrs old. Anaphylactic "SHOCK" is survivable "IF" treated as soon as it starts and quickly. Once you see Anaphylactic Shock, you will never forget it. Their eyes turn beet red (even if they're normally black) and so does their skin, ALL the hair on their bodies stands straight out like a bottle brush and stiff. They were rigid and sometimes they salivateted, but they were always unresponsive to stimuli. Two of them almost died if it were not for our vet. The first one that was a year old did die, but our vet was able to bring him back due to his quick thinking. Anaphylactic Shock (not an allergic reaction) is fatal if you do not know what to look for and treat it ASAP. This is the only time it is survivable. This is why we encourage people to ask their vet to give the vaccine "FIRST" and then do the physical exam as well as having distemper and raibies shots done at different times. ( This way you will know what your furkid IS reacting to. This way you will already be at the vets office about 30-45 minutes. Debi [Posted in FML issue 5160]
