I came home from work tonight and went over to my boys' cage and noticed some blood. I checked both of them out and one of them and some coloration from his anus area to a little on his tail. I'm wondering if I need to take him to the emergency vet ($100 to walk in the door) or if I should give him some CriticalCare. I've never been through the blood situation before, so I'm hoping for some advice for my little guy! Thanks everyone!
