The most common cause of a male cat having a hanging belly is obesity. Like humans, cats can become overweight if they don’t get enough exercise and eat too much food. If your cat’s belly is visibly hanging down low, it’s a sign that it’s carrying too much weight. To help your cat get back to a healthy weight, make sure you’re feeding it a balanced diet and providing plenty of opportunities for exercise. Another potential cause of a hanging belly in male cats is the presence of an enlarged abdomen. This can be caused by a variety of conditions, including heart disease, kidney disease, or even a tumor. If your cat’s belly suddenly starts to hang lower than usual, make sure to get it checked out by a veterinarian as soon as possible. Finally, a male cat’s hanging belly could also be due to the presence of fluid in the abdomen. This can be caused by conditions such as liver failure, pancreatitis, or cancer. Again, if you notice that your cat’s belly is hanging lower than usual, make sure to take it to the vet for a check-up.
