Different types of bloody stool

Cats have a variety of bloody stools. The most common is having a normal, regular stool with red blood mixed inside or outside the stool.

Many cats sometimes have mild bloody stools and may not have serious problems. Red blood cells usually develop in the lower digestive tract, the colon. Cats can cause colon irritation for several reasons.

There are more notable problems if your cat’s stool is soft, dull, or contains red blood mixed. This issue should be checked as soon as possible.

The last situation is when you see dark red or black stools inside or on the stools. Dark blood means that it has been partially digested and can come from higher gastrointestinal tract parts. If you notice this, take your cat to the vet immediately.
