Cat Bloody Diarrhea Stress. Sometimes when they are disrupted, a cat’s diarrhea will continue even after the initial insult (stress, disease, antibiotic therapy, etc.) has resolved. In most cases, it is your cat’s diet that is at fault.
Here’s how you can help relieve the causes. As a cat lover, you probably know what this means. Stress can send your kitty running for the litter box, if you're lucky, to leave the occasional messy puddle of poo behind.
It is always alarming when we discover blood in your cat’s stool, but in a lot of cases, the cause is minor and transient.
Acute diarrhea means that it started suddenly. Consult your veterinarian for advice. In humans, this is often a serious issue. Stress can also cause diarrhea.
