My new guinea pig (currently no-name) I think has something wrong with him. I've had him since 3 p.m. yesterday and the whole time has been pooping uncontrollably! He gets the poo stuck all in his fur and it's really mushy. The lady I adopted him from said that she noticed it but she said it was because he ate to much fruit. But it's just so much! It's mushy and smells horrible! I don't know what to do because all the vets are closed. I don't know if I should just give him back, but it would be very hard to do because already love him so much. Please help!
