Sorry for the gross pictures, I just wanted to be sure. My other Guinea pig (both female) had a similar problem a few months before she passed. They're both are (and was) pretty young. Probably around 6 years old. Anyways, her genitals are pretty tender and she screams whenever I touch around it. I heard her wining in her cage earlier, and it worried me. I can't get to a vet right away because of financial issues, but I just cleaned her cage and gave her fresh hay. Do you guys know what it might be? Should I worry or is it just a scrape or irritation? She peed earlier but it wasn't very much.
