Cavy Kung-Fu
Adult Guinea Pig
He found one, he stuck some tape to some areas where there were flaky bits of skin. They were barely visible to the naked eye. He had to put it under the microscope to check but he found it. The wounds aren't caused by the mites but them scratching. Stripe had a scab too. They both got weighed, gender checked and some mite drops, they have to go back to see if their scabs heal, if not they might go on antibiotics.
Aww, sounds like you caught it pretty early though! Hopefully they'll be free of them soon
