Cats are generally active and able to regulate the amount of food they eat. In the wild, cats spend 6-8 hours daily hunting and are only successful 10-15% of the time they try and catch a bird or mouse. So, lots of running around for a bite to eat! However, there is an increasing trend for modern cats, like modern man, to eat more high fat food and take less exercise than their predecessors. Gourmet cat foods are delicious and "easy to catch", and we like to pamper our pet with what we consider the best. Just as in people there is a risk that your cat may become overweight. Obesity is an excessive accumulation of fat in the body that adversely affects health - it does not just mean being overweight.
