Incidentally caught this possum in Seattle on a nuisance raccoon job. When I first saw him I thought he must have a horrendous prolapse but when I looked I saw it was a bulging wound or tumor on his tail. This possum was also blind in one eye and in otherwise poor condition. Thinking a biologist might want to see this, or that I should at least report it, I called WDFW Region 4 office. Customer Service there said a biologist wouldn't need to see it unless there were multiple cases. So, is anyone else out there seeing animals with a condition like this? Anyone know what this really is?
