I think maybe a lot of MF ferrets given maybe less that optimal care DO last only 5 years. Other ferrets from other places may live as long as 12 years. The important variable is....how you KEEP your ferrets! Clean, on a high-quality ferret food, regular vet checks, every 6 mos after about 3 years old..........But I, personally, have not had a ferret reach the age of six yet, so I am no fount of wisdom! I just wish that they had a longer life-and base my belief that they DO on the condition of my OLDEST and BEST LOVED rescues! They are like 2 year olds still, at 4-5 years old! I can't believe they will suddenly succomb! Keep in touch-hope the news is good! Karen [Posted in FML issue 2159]
