Golly, of course animals have emotions! I had 2 dogs that I loved very much (I still miss them) and they let me know when they were happy or sad... When they were upset or angry with me (for leaving them alone too long)..
Self-aware? My dogs would lick their wounds.. They knew what hurt and most of the time (depending on the situation), knew how to heal their own wounds..
One of my dogs loved to eat charcoal and I found out the medical reason for that.. but that's another story...
Sunnyman, I didn't know that most animals can produce Vitamin C, that so interesting!
Animals are healing to one's soul... At least to my soul...
Funny, whenever I met someone and introduced that person to my animals, my animals let me know if that person was not nice or very nice (amazing sense they have!).. I would never be friends with a human that did not like animals... But that's me..
