Took him to the vet, it is ringworm. We have no idea though how he could have gotten it. He stays indoors all the time and it's never with other pets. The vet thinks it could possibly have been on the hay?
My boy is almost 10, seems fine in every way except tonight we noticed that his testicles have a white scab like appearance covering most of them. I have already scheduled a vet appt asap but curious if anyone knows what this is.
