What are the causes of bloody stool in cats?

1. Constipation and indigestion blood stool

1. Constipation causes blood stool

There are two types of constipation. Primary constipation is caused by factors such as single food types, insufficient drinking water or insufficient exercise. The lumbar spine deformation caused by intestinal dislocation, accumulation of undiluted foods in the intestines, or severe calcium deficiency, is secondary constipation, which may cause bloody stools.

2. Causes of indigestion

Cats eat abnormal diet, eat too much food, or are not suitable for food, which is easy to occur during the kitten period. When the stool is light yellow and has a sour smell, or even bloody, you can fast for seven or eight hours first, and then condition it with probiotics.

Treatment: Primary constipation can be treated with enema. If it is severe constipation, the veterinarian must be given surgery. The method to prevent constipation is to ensure sufficient and fresh water during daily feeding. Pay attention to the food combination of cats. You can add some pet-based probiotics to improve the gastrointestinal flora and help cats digest and absorb the gastrointestinal intestines.

2. Parasites and gastroenteritis in the body

When there are parasites in the cat's body, green worms will attach to the small intestinal membrane, causing mucosal damage, causing intestinal inflammation, and even causing intestinal mucosa bleeding. When green worms continue to stimulate the intestinal tract, causing intestinal dysfunction, diarrhea or blood.

Treatment: When a cat is three months old, it is necessary to deworm its body, but pay special attention. When helping the cat deworm, be sure to ensure that the cat is in a healthy state. If the upper abdomen diarrhea occurs, take the Pet Probiotics first, and then deworm them after recovery.

3. The occurrence of gastroenteritis

Compared with the previous blood stool caused by indigestion, the stomach will not only be severe, but also contain pus and blood in the stool. The treatment of gastroenteritis is mainly based on systemic anti-inflammatory and symptomatic treatment. The general treatment time will not be too long, and the normal time is within one week.

The diarrhea is very severe, the feces are smelly, and most of them are bloody, and cats will vomit violently, not eat, and have poor spirits. The more likely cat plague is to cause death in young cats, it must be treated in time to allow white blood cells to return to the normal range.

2. Judgment of bleeding conditions

You can determine the bleeding site according to the color of the poop. If the feces are black like asphalt, the bleeding location is in the stomach and small intestine. If it appears bright red or dark red, it means that the stay in the intestine is short, and the bleeding is in the posterior intestine, like the large intestine.

Owners must control the maintenance of cats, choose healthy and easy-to-digest foods, and avoid hard and irritating foods. The most appropriate foods are cat food and other cat foods. They should also regularly deworm and check them both inside and outside the cat.
