What are three examples of selfishness in "Animal Farm?"

As others
have mentioned, the pigs have more or less cornered the market on selfishnessbut not entirely.
Mollie shows her selfishness when she shirks her duty by getting up late and leaving work early.
She will only learn the letters of her name and no others. She hides lumps of sugar and ribbons
for herself. She finally goes back to pulling a cart for a human. Mollie is interested in her

comfort.

The cat disappears when it is time for work and then shows up for
meals, also not pulling her weight.
