It's obvious why this cat goes by the name 'Ugly Bat Boy'. Uggs as the cat was known, lived at the Exeter Veterinary Hospital. Most of his time he would spend on a warm computer. He only had fluffy fur on his chest.
Last year the vets discovered Uggs had a heart condition. According to Dr. Bassett that cats with this type of heart disease, they can just suddenly throw an arrhythmia and pass. That is exactly what happened to Uggs.
