* Gray squirrels are known for their gray fur with a white belly.
* Eastern gray squirrels can sometimes have a few white patches, but these are not typically on their fronts.
* Albino gray squirrels exist, but they are extremely rare and have completely white fur, including their fronts.
If you see a squirrel with a white front, it's likely a different species, such as a fox squirrel which has a white belly and chest.
