Feline lower urinary tract disease (FLUTD) is a term that is used to cover many problems of the feline urinary tract, including stones and cystitis. The term feline urologic syndrome (FUS) is an older term which is still sometimes used for this condition. The condition can lead to plugged-penis syndrome also known as blocked cat syndrome.




Jaundice is characterized by yellowing of the skin and the sclera or whites of the eyes. It is not a disease but only a sign to many other different diseases. Jaundice is caused by the high level of chemical bilirubin in the blood. Depending on the level of the chemical, the yellow pigmentation of the skin and the sclera may vary. When it is too high, it could appear as brown and not yellow.
