1. Subspecies of the Snake

Milk snakes make good pets, but they are not created equal. There are over 24 recognized subspecies of milk snakes. Each of them has a distinct size range. The eastern milksnake, for example, is smaller in size compared to the California Kingsnake

Knowing the specific subspecies of your milk snake, therefore, is important while purchasing them. You can have a general idea of how long it may get once the reptile grows up. 

2. Sex of Your Pet

Sex plays a vital role in determining the size of the snake. This is called sexual dimorphism, where one sex is noticeably larger than the other. This is present in many milk snake subspecies. 

Females are generally larger than males. The differences become more pronounced as they reach adulthood. The larger size of the female may be because of their need for more space to store developing eggs. 

3. Genetics

Genetics plays a significant role in determining a milk snake’s overall size. Selective breeding in captivity can influence size. Breeders often focus on specific traits like larger size for certain morphs. However, these practices should not compromise the snake’s health or natural proportions. 

4. Diet and Nutrition

Just like with humans, proper diet and nutrition impact a milk snake’s growth. A healthy diet consisting of appropriately sized prey items ensures they receive the necessary nutrients. Note that milk snakes do not drink milk

Nonetheless, overfeeding should be avoided. Feeding more than needed can lead to obesity and potential health problems. Don’t do this to enhance their sizes. Providing a balanced diet is crucial for a healthy and appropriately sized milk snake.

However, the growth rate can be influenced by factors like genetics, diet, and overall health. A well-fed snake with good genes will likely reach its full size faster than one with an inadequate diet or underlying health issues.
