Yes, they can be albinos if they have deep red pink eyes & if they are snow white all over the chances are great. The eyes look pink when sunlight hits them but in regular light have a red pink look to them.

Years ago a nest of baby squirrels were knocked out a Burr Oak tree in our yard by a buck squirrel. We raised the babies & one was an albino that had the red pink eyes. We named him Pinky & eventually he was released along with his siblings.

I also saw an albino climb down a tree years ago at the Minnesota State Fair while I was sitting on the lawn watching a band play in the band shell. The albino squirrel just hopped right on by me.
It was around that time a year before, my dad had passed away & I sometimes wonder about that happening? He was always kind & caring of the wild animals & taught us the same.
