Tortoise illnesses why is my tortoise swollen and bleeding from its rearend?

The tortoise probably has something called a prolapsed cloacea. It needs to go to a veterinarian immediately. This is not only very painful, but it's also fatal if not properly taken care of. This can be caused by straining while having a bowel movement, laying eggs, a parasite or a tumor. Whatever the case is, it needs to be taken care of immediately, and preferably with a herpetologist veterinarian
