Why is my cat peeing on the bed?

Peeing on soft surfaces like beds is often a sign of a medical problem (bladder inflammation, infection, crystals, kidney disease or diabetes) or stress.

First: see a vet to rule out urinary problems. A male cat straining with little urine is an emergency.

Then check the litter box: one more box than the number of cats, scooped daily, unscented litter, quiet location. Clean soiled areas with an enzyme cleaner.
