By the end of their first week, what change may occur in baby grey squirrels?

• A. They may begin to gray on the head and tail
• B. They grow fur bright orange
• C. They can stand and walk
• D. They can open their eyes

Answer: (A)

Baby grey squirrels develop the coat early, with coloration first appearing on exposed areas like the head and tail during the first week. At birth they’re hairless and unable to see or move well, so the first noticeable change is the growth of fur and the emergence of the gray color on those areas. Eyes remain closed for several weeks, and true locomotion comes later, so options about standing, walking, or opening eyes by week one don’t fit. A subtle early gray on the head and tail reflects the initial stage of coat development, making it the best description of what occurs by the end of the first week.
