question:
Earlier in the week , I heard a rhythmic scratching noise outside my bedroom window . Upon further investigation , I discovered it was a fat squirrel eating something as large as his head . The object was pale , cylindrical , and hollow . He left his chew toy behind on the front porch , so I investigated . The squirrel had been gnawing on a bone . The bone looked like a short section of femur with the marrow long gone or a rounded - off vertebra . 
Question: What's a possible reason the fat squirrel was chewing on a bone ?
answer:

There was some meat on the bone to eat .
