My guinea pig, Mocha, started passing blood when she would eliminate. She cried out in pain when she urinated or was passing pellets. I would see blood in her cage. She was very sick by the time I got her to the Vet. I placed the transducer on her stomach and sides (Mind). Stopped bleeding and became healthy again. She fully recovered. Gained her weight back and playing again.
