If your cat is always hungry and gobbles food down quickly and looks for more, s/he could have a condition called polyphagia, excessive eating. Polyphagia is usually a result of an underlying condition.
Does your cat exhibit behaviors such as vomiting after downing a meal quickly, eating anything offered (even food s/he has refused previously), always looking for more food, counter-surfing, begging or stealing food wherever it can be found and generally appearing constantly hungry?
Most cats display some of these behaviors at one time or another, but when they become excessive, there is a problem. The problem will not be solved by offering more food or ignoring your cat’s demands.
There are diseases that cause exessive hunger in cats.
Hyperthyroidism is an overactive thyroid. A higher release of thyroid hormones increases metabolism.
Diabetes Mellitis occurs when too much or too little insulin is released by the pancreas.
