In Animal Farm, why does Mollie leave the farm?

In
, Mollie does not give a reason for leaving the farm. However, by looking
at chapter five, we can infer some reasons why she disappeared without warning.

For a start, we know that Mollie was the sort of animal who enjoyed being fussed over
by her owners. She also loved wearing ribbons and eating cubes of sugar. When the animals
expelled Jones from the farm, life for Mollie changed significantly because the wearing of
ribbons and the eating of sugar cubes were no longer favored activities. Moreover, as we learn
from the opening of chapter five, Mollie was not interested in doing any of the work required to
maintain the farm and would often make excuses to get out of doing it.

What
we can infer, then, is that Mollie leaves the farm because it no longer shares her...
