What is the average weight of a cat?

Almost 50% of the cats in Britain are overweight. This is because cats often get too little exercise and too much food. Especially housecats that always stay inside are often overweight. This results in that these cats die at a younger age. The normal weight of a cat, depends on many factors such as sex, breed and age. In general we assume that the average weight of a healthy full-grown cat is about 7.7 pounds (3.5 kilo).
