Welcome to the forum! Sorry for the delayed response!
A trip to the vet revealed that Malachite had a gram negative bacterial infection. He was prescribed Ciproflaxin which was given orally once a day. The infection did clear up, however Malachite passed away not too long afterwards. The necropsy revealed that he had carcinoma of the liver which can only be diagnosed postmortem. The infection was just a secondary result of the cancer.
We have since learned that mucus in urine/feces can be caused by just about anything that irritates their intestinal tract: Bacterial infections, parasites, impaction, dehydration, malnutrition/vitamin deficiencies, etc. We really need more information, but I recommend consulting a vet.
