What are the symptoms of feline lower urinary tract disease (FLUTD), and how do I prevent it?

Quick answer

This is a very common, frequently recurring condition in cats. Suspect it if your cat visits the litter box often but only passes a small amount of urine, cries out while urinating, has blood-tinged (pink/red) urine, or has an accident on bedding outside the litter box. Stress and insufficient water intake are the main causes, so make sure your cat drinks enough water and keep the litter box clean at all times.
