So a couple days ago I noticed that Umbra had some flaking around the edges (and later the back) of her ears, accompanied by hair loss. After some research in HRS's health resources, I'm thinking that Umbra has either fur mites or ringworm. Neither is very serious, but nonetheless we are going to take a trip to the vet tomorrow afternoon... I'm sure Umbra will be thrilled.
More tomorrow when we hear the doc's diagnosis.
