...and then I went to the pet store. The snakes there currently most definitely have mites I alerted one of the staff, who was surprised and asked how I could tell, and now I can only hope they treat the problem with the correct product. They had a little pastel girl that looked pretty sad and thin, and a few looked like they had bed sheds in their future... Maybe I shouldn't be surprised, but I am.
Are mites very common, or is this just a stereotypical big chain pet store problem? Also, do you guys think they will treat the snakes?
