I once came home to find my baby Naco running around the
cage during the day in a panic. After taking him out I realized there
was blood all over the cage and his tail. From what I can see it
had gotten caught on the bars of the metal cage. Poor little guy,
I brought him to the vet ASAP and they had to amputate part of his tail.
He recovered just fine. He still is in a metal cage and luckily neither
him or his girlfriend Gamma have gotten their tail caught since.
