According to Squirrel Store, baby squirrels start to develop soft, reddish, sable hair around the nose and mouth at 5 to 10 days old. They will open their eyes between four to five weeks.
Guide on how to determine the age of a baby squirrel:
- 1 to 5 days - tiny, the size of a woman's thumb - knuckle to tip - and totally pink; no hair at all.
- 5 to 10 days - development of soft, reddish, sable hair around nose and mouth.
- 10 days to 2 weeks - a grayish purple shadow begins spreading over the head, shoulders, and back; the belly and legs are still bright pink.
- 2 to 3 weeks - grayish-purple color deepens until the emerging hair is long enough to be identified as hair.
- 3 weeks - the baby's lower front teeth begin emerging. Hair is now slick, smooth, and shiny. Still no hair on legs and belly.
