Why does our pets love unconditionally?

Not for a second will I believe animals have no feelings! I have seen a wide range of emotions/feelings in animals... dogs lately. Some are aggressive and I believe that may be because some are abused.... others cower and are afraid... while others jump for joy, tails wagging, etc...

SkyWalker7.... if you have a pet or pets that love you unconditionally, it's because you gave them all the right things for them to feel that way... kindness, care, attention and love.

I wish more people gave animals credit for more. :)

Animals don’t have the brain functions to make feelings of hatred, jealousy, or other complex emotions. Those and others are unique to humans. Animals, domesticated ones especially, simply enjoy our company.
