If you are in the market and looking to buy a cage for your pet ferret, keep in mind the following information: the average size of a ferret is approximately 20 inches with an average weight between 3 to 5 pounds when full grown. Even though 20 inches is not very big, you still should consider buying your ferret a medium to large cage. The reason being is that ferret’s need to roam around and as such, they need lots of space to do so. Which is why there are various sizes from small ferret cages to 4 level cages. It’s kind of like the equivalent of living in a small one room apartment versus a mufti-level home. Which would you be happier in? Keep this in mind if you are considering a small ferret cage.
