Other symptoms of kidney failure in cats include frequent urination, excessive thirst, mouth ulcers, a dark-colored tongue and bad breath, says WebMD. These are signs of either acute renal failure or chronic kidney disease. Acute renal failure can affect cats of any age and is often caused by kidney infection, heart failure, trauma and poison ingestion. Chronic kidney disease occurs mostly in older cats because of kidney blockages, thyroid issues or cancer. If diagnosed early, acute renal failure can be cured. Cats with chronic kidney disease may have their lives prolonged with the right diet.

Blood in the stool is symptomatic of liver failure, states PetMD. Other symptoms of liver failure include diarrhea, jaundice and vomiting. Liver failure may lead to problems with the kidneys, lymphatic system, nervous system and gallbladder. For instance, liver failure can affect the brain, leading to encephalopathy or brain disease. The toxins that the liver fails to remove from the body can infect the kidneys and imbalance the blood. The tissue and cells in the liver and gallbladder start to die, leading to necrosis.
