I looked at the post from the Ferret-L Digest on Feb 17-18 and I noticed that the ash content is at 12%. This seems to me to be very high. I am not a veterinarian but everywhere I have read and heard from my vet that for ferrets the ash content should be less than 6% or they can develop urinary tract blockages. Anyone else here know anything else about ash content and how it relates to ferret diet and health?? Dom [Posted in FML issue 4427]
