knowing if your cat's poop is healthy or not

The majority of cats defecate once a day. Your cat’s normal feces would usually be about 7 centimeters, well-formed, brow to dark brown, and not too strong in smell. According to U.K’s Waltham Center for Pet Nutrition, there is a Feces Scoring System, which they developed. Checking this chart would help you define whether your cat’s feces are abnormal or not.

How do I notice if there is blood in my cat’s stool? Is it always clear?

Blood or mucus in your cat’s feces can be hard and challenging to spot for many reasons. The litter in the litter box can conceal it, or create some changes and deformations to its appearance. Blood can also be different in color depending on which part of the body it is coming from.

If the bleeding were from the small intestines, in the higher intestinal tract, the blood would be darker than the usual blood we know, it would be either black or brown. Digestive enzymes in the small intestines cause this change in color. You would notice these brown or black blood spears like coffee grounds or specks in your cat’s litter box or around it.

However, if the blood were coming from the lower intestinal tract, the large intestines, or also known as the distal colon, it would be more like the blood we are all familiar with. Blood from the lower intestinal tract would be red or pinkish, you find these blood spots on the feces, in the litter, or even around the litter box.

What should I do?

If your cat displays any of the mentioned symptoms, you must take it to the veterinarian immediately. If these conditions are ignored, they could become complications and risk your cat’s life. Make sure you check your cat’s stool occasionally for any abnormalities.

How to treat rectal bleeding in cats?

Most cases in cats, which cause bleeding from the rectum, can be treated with medications, and only a few of them require surgery. It is better to tale a sample of your cat’s feces to the veterinarian before your prior appointment. Your vet would run some tests to identify the source of the problem and check for worms as well.

Conclusion:

Our cats would try to tell us whenever they are facing a health problem. They would display a change in behavior or vocalize some abnormal sounds. However, your cat’s feces would tell you a lot about your cat’s health conditions as well. Many pet parents check their cat’s litter box occasionally looking for any abnormalities in their cat’s feces. Your cat’s poop says a lot, and sometimes, you can find traces of blood in the feces or around the litter box.

This can be due to many health issues such as the following: a change in the dietary system, rectal polyps and tumors, physical injury or trauma, anal sac disease, internal parasites, anticoagulant poisoning, and other reasons that can cause your cat to bleed from its rectum.

Your cat’s blood color would depend on where it is coming from. If it is coming from the higher intestinal tract, the blood will be dark brown or black, while if it is coming from the lower intestinal tract area, the blood will look red or pink. The blood color could tell a lot about your cat’s condition.

If you notice your cat displaying any health conditions such as vomiting, weight loss, or difficulty in breathing in addition to blood in the stool, you should take it to the veterinarian immediately. Ignoring your cat’s condition could lead to severe complications, and eventually kill your cat if you do not provide it with the proper medical care when it is bleeding from its rectum.
