You have probably noticed that there are many different names for the different sizes of feeder mice such as pinky mice, fuzzy mice, medium mice, etc., but do you know what each of these names mean and how they compare in size to one another?

At RodentPro.com, we offer fresh, high quality frozen feeder mice in various sizes to meet your animal’s needs. The size of the mouse you need is dependent upon the size of the animal you are feeding. Keep in mind that different sizes of mice have different nutritional compositions. The nutritional compositions of white, dark and hairless mice are the same. Learn more below about the various sizes of feeder mice we have available.

Remember this rule of thumb for choosing the right size of feeder mice for snakes: Choose a size that is equivalent to the widest section of your snake’s body. If you are unclear as to what size is most appropriate for your snake, it is always best to choose a size too small as opposed to a size that is too large as you will risk causing the snake to regurgitate the mouse.


Pinky Mice
Extra-Small Pinky: Extra-small pinky mice are generally 1 day old and range in weight from 1.50-1.99 grams. They are called pinkies because they appear pink in color, as they have not formed a coat of fur yet

Small Pinky: Small pinky mice are generally 1-2 days old and range in weight from 2.00-2.49 grams. They are called pinkies because they appear pink in color, as they have not formed a coat of fur yet.

Large Pinky: Large pinky mice are generally 3-4 days old and vary in size from 0.50”- 1.00” long, not including tail length and weigh 2.50-2.99 grams. They are called pinkies because they appear pink in color, as they have not formed a coat of fur yet. This is the last stage a mouse is considered a neonatal mouse before being considered a juvenile.


Fuzzy Mice
Small Fuzzy: Small fuzzy mice, sometimes known as peach fuzzies are generally 5-9 days of age and range in weight from 3.00-4.49 grams. They may be starting to develop a slight coat of white or dark fur. These would be the perfect size for those animals in which the pinkies are too small, but the regular fuzzies are too large.
