Intestinal problems
As you probably know, intestinal problems can increase or decrease your pet’s appetite, but if you notice that your cat wants to eat all the time, it may have to do with irritable bowel syndrome.
“It depends on the primary cause of the intestinal disease, but if we’re dealing with an increased appetite, it could be because of the level of inflammation is affecting the cat’s ability to digest and absorb nutrients, and it may need to take in a higher level of food to compensate for that,” said Murphy.
According to Dr. Mazepa, “disease that affects the small intestine results in an inability to absorb nutrients,” she says. “Because of this, the cat will lose nutrients from food in the stool, which results in an increased appetite and weight loss.”
If you notice any symptoms, try to talk to your vet about treatment and medications.
