When we talk about “size”, we generally think of dogs. An adult dog can be many times larger than its puppy size. And yet, cats also grow, of course. And so, just out of curiosity, have you ever wondered how long and how much a cat grows? The question is also raised by “Catster.com”, from which we have some information about it.
The growth of puppies is, as also happens to our children, quite rapid in the early stages. A kitten can change from day to night in a few weeks. If at about a week after birth it weighs about 113 grams, at 5 weeks it can reach 450 grams. And at 16 weeks of age, she can grow to weigh as much as 3.5 kilos. These numbers are obviously estimates, so the advice is always to consult your vet to check the puppy’s proper development.
As a guideline, the cat reaches its almost final size between 6 and 12 months. Even at six months, you have a pretty good idea of what it will look like as an adult.
This, of course, as far as the natural physical conformation is concerned. A moderate intake of food, combined with little exercise, can change this.
One of the exceptions to this axiom is the Maine Coon, which due to its exceptional size can grow in tonnage even up to 5 years of age.
However, this only partially answers the initial question, i.e. how long and how much a cat grows.
For example, the question is whether it is possible to predict the weight of the future adult cat. This factor depends primarily on genetics, ergo it is possible to make an estimate based on the physical conformation of the parents if we are aware of their identity. Failing this, the breed, whether we are dealing with a cat of breed or a cross, is certainly a good indication. The most striking example, in this sense, is certainly the Maine Coon. What is certain is that the size of the legs is not, contrary to what happens with dogs, a reliable element.
Generally speaking, the final weight generally ranges from 4.5 to 9 kilograms.
Cats are not free from dwarfism, so there are specific cases where growth takes a different drift. This is the case of Lilieput, the current holder of the “World’s Lowest Cat” record. Measuring from floor to shoulder, he measures 13.34 cm.
