One of the juvenile squirrels in my tree (he is there with two siblings and his mother) has pox. So does mom and I am not sure about the other two. The juvie in question has a large pink mass dangling from his tummy about the size of a gumball and what looks like another mass right below that. I am posting a couple of videos so you can see the condition. He is wild so it is the best I can do.
