From the book, Wesley the Owl,
by Stacey O'Brien
"We repress, deny, subjugate, disassociate, and use all kinds of conscious and unconscious machinations to separate ourselves from our feelings, but animals have no recourse, so their emotions are raw and strong.
The evidence that all species of animals with a brain have emotions is overwhelming. Lack of stimulation affects brain growth. The more intelligent an animal is, the more he has complex emotions."
Thank you, Stacey. This says it all.
