I left my cat alone from eight in the morning the week school started again: three days later, the red streaks in the litter had nothing to do with an infection
When a cat suddenly bleeds in the litter tray, the culprit is rarely what owners expect. Feline idiopathic cystitis—a stress-driven bladder inflammation with no bacterial cause—is far more common than infection, and it’s often triggered by something as seemingly minor as a change in daily routine. Understanding what’s happening inside the bladder, and why back-to-school timing is no coincidence, could save your cat from unnecessary antibiotics and yourself from unnecessary panic.
