Hi, My Cham is about 6 months. He has stopped eating, not moving around much, barely drinking. He has a bump under his skin near the end of his back(spine) near where his tail starts. Recently he has started leaking a yellowy slimy substance out of his butt. It also appears his butt may be swollen and he hasn't been pooping or anything.... Help! I can't get to a vet until next week. Is there any meds I can give ? Could it be constipation? Are there any laxatives? I've already tried putting together for in warm bath. A little of the yellow stuff came out.
