What to do if your cat has blood in its urine?

You need to take your cat to the vet immediately. Blood in urine usually means Cystitis (inflammation of the bladder), or some other bladder problem. This condition, much like human bladder infections, is very painful for the cat and in some cases (such as a blockage) can be life-threatening if not treated.

Cats usually develop urinary problems from stress or not drinking enough water and the urine becomes too concentrated. This can occur if the cat is fed only dry food (a cat has evolved to get moisture from its food and so have a low "thirst drive") or overly stressed.

The most important treatment, aside from vet-prescribed pain killers (and antibiotics if an infection is present), is to increase your cat's water intake. Another treatment is herbal medicine like Diuretic and Anti-inflammatory Pill to eliminate inflammation, kill bacteria, clear heat and promote blood circulation etc. Feeding wet food instead of dry, adding a little extra water to the wet food and/or providing a water fountain to entice the cat to drink more water are very good options. Even adding "flavoured water" such as juice from canned fish to food or water will help entice a cat to drink.
