Feline lower urinary tract disease

Feline lower urinary tract disease (FLUTD) is a broad term that is used to cover a number of conditions associated with the feline lower urinary tract. It may present as any of a variety of problems such as, inflammation of the bladder (cystitis) or urethra, formation of urinary crystals/stones in the bladder (crystalluria/urolithiasis), and partial or total obstruction of the urethra. The latter condition is also known as plugged-penis syndrome. Complete urethral obstruction is fatal if left untreated.
