In terms of their actual growth, Siamese cats will typically stop growing after 10 to 12 months, although some outliers do continue growth for a few months after this.
A few other factors influence how large or small your Siamese cat might grow.
In general, cats will grow within the stated range of length and height. But aside from genetics, these factors have been found to have so impact on their eventual size.
An average Siamese male cat can weigh up to 14 pounds. On the other hand, a female generally weighs up to 11 pounds.
This is the most significant size difference between genders, and the male and female lengths and heights are only marginally different – think less than a half-inch on average.
Nutritious cat food and clean, fresh water significantly impact the body and its organs. It should be no surprise that kittens who eat well will grow stronger and probably slightly larger than underfed or malnourished ones.
If you see more aggressive kittens dominate the food and water, they will grow more potent than others, who may become smaller as a result. This is also partly why feral kitties are more diminutive than domestic cats.
Some experts believe that the first few weeks of proper parental presence (mom cat) are critical for good early development.
