Cattail is a month old rat that had the skin stripped from the end of his tail (degloving injury). The tail bone in the stump prevents the skin from growing over the end and it stays a wound for months or years. So we sedated him which allowed amputation of the tail bone further down so the skin can grow over. If he keeps the bandage on for a few days it will heal quick. he has youth on his side. Cattail is very tame and friendly, and for those of you that are skeptical, RATS MAKE GREAT PETS!
