Weasels Vs. Ferrets – Habitat and Behavior

Did you know that there are two distinct species under the Mustelidae family? Weasels and ferrets are remarkable mammals that share biological similarities. They both have long bodies, and short legs, varying in size depending on their breed and type. 

Interestingly, weasels primarily reside in regions with cooler climates, such as Europe, Asia, Greenland, North America, and Japan. Meanwhile, ferrets can be found worldwide. Behavior-wise, both species are known for being curious creatures who love to explore and take part in curious activities. 

Despite their small body sizes, they have impressive hunting skills. They will often hunt mice or insects for food when given the opportunity. In addition to these behavioral patterns, weasels and ferrets are intelligent animals with fascinating social structures.

Physical Characteristics 



  • Small, slender-bodied mammals with short legs and long, thin tails.
  • Typically weigh between 1-2 pounds (0.5-1 kg.)
  • Have short, dense fur that is brown or black on the back, and white on the belly.
  • Have a pointed snout and small ears.
  • Are agile and fast runners, able to climb trees and swim.
  • Have sharp teeth and claws for catching and killing prey.


  • Slightly larger than weasels, with long, slender bodies and short, furry tails.
  • Typically weigh between 1.5-4 pounds (0.7-2 kg).
  • Have a wide range of fur colors, including black, white, brown, and mixed patterns.
  • Have a rounder snout and larger ears than weasels.
  • Are agile and playful, known for their acrobatic abilities and love of toys.
  • Have sharp teeth and claws, but are typically not used for hunting as they are domesticated pets.

Overall, weasels and ferrets share some physical traits but differ in size, fur coloration, and behavior.

Differences in Feeding Habits

Contrary to popular belief, there is a big difference between the eating habits of weasels and ferrets. Weasels are carnivorous mammals that typically feed on small rodents, eggs, and insects. 

On the other hand, ferrets have modified diets that allow them to consume a combination of meat-based proteins, grains, and vegetables.

Additionally, a high-quality ferret diet should be nutritionally balanced with essential vitamins and minerals for optimal health, something not found in the wild diet of weasels. 

Despite their different eating habits, both animals require fresh water daily to stay healthy and hydrated. 

Examining their Social Behaviors


When investigating the social behaviors of Weasels and Ferrets, we may be surprised to find that these two small mammals are surprisingly big on social interaction. From research initiatives such as observing ferret families in their natural habitat, it has been determined that both weasels and ferrets live in cohesive family units with each other. 

This means they both interact closely on a daily basis with their family members and other individuals in the areas. This shared social behavior indicates the relatedness between these two close cousins of the Mustelid family. Such interactions can range from animals playing together or even grooming each other’s fur through mutual grooming.

Through these observations, specific common trends of behavior between the animals can be found. This allows us to see not just how weasels and ferrets interact with each other but also how essential socializing is for all creatures around us.

Hunting Abilities and Natural Instincts

When it comes to their instincts, their similarities can be deceiving. Weasels are much more active hunters and prefer open areas and daytime hunting. 

On the other hand, ferrets are more suited to smaller enclosed spaces where they can hunt over more extended periods due to their smaller size and powerful potential for scent tracking. 

Understanding the impact of these instinctual differences on hunting could help us spot either of these creatures in the wild more easily.

Do Weasels or Ferrets Make Better Pets?


Sadly, weasels are known to be pretty aggressive and are therefore highly unsuitable as pets. In most U.S. states it is even illegal to keep them as pets since they are deemed wild and exotic animals. Because they are so active they require a large amount of space to explore, so they do not adjust well to living in a domestic environment.

Additionally, weasels are known to be destructive and can cause damage to furniture, carpets, and other household items. Furthermore, they require specialized diets that may be difficult to meet in a domestic setting. For these reasons, weasels are not recommended as pets.

Ferrets, on the other hand, are popular pets because they are extremely social and playful. However, they require plenty of specialized care, such as a high-quality diet, regular vet visits, and regular grooming. They should also be spayed or neutered, and kept in a secure cage when not supervised.

The ferret has significant energy levels and are very playful animals – as a result, they need plenty of toys and interactive activities to keep them entertained. Try to provide a variety of different toys and rotate them every few days to keep your ferret interested.
