Animals also experience emotions. In their eyes, you can easily read the sadness, the hopelessness and joy, and love. They understand what it means to survive on the street, living in shelters or becoming a member of a loving family.
You only see what sincere joy and real emotions appear in animals when they acquire the home and family. This kitten eyes changed after he left the shelter walls. He eked out a miserable existence in the orphanage where it was going to be put down.
The chances that someone will pick up were minimal. Too miserable looked like this cat. But that all changed just a few weeks.
