It is a tough call. To say that animals share the same feelings, thought processes, and capacity to care as people, would upset me. If it were true, I would feel bad about killing animals for food; it would be akin to eating a person, no?
I believe that certain types of animals can be "invested in" and taught to care for and become attached to a certain person or people in general. With many animals, the link to food is what attaches them to humans. Take my friend's geese. They dislike people and run away from you, bu if you toss out some grain, they run up to you and will even follow you around if they know you have food. Same with my chickens.
Mammals are different though. To me, they seem to posess a greater capacity to bond to humans and care about us in general. My cat is attached to me; he sleeps right by my head, and when I am home he is my shadow. Is this love, or is he waiting for me to get him a kitty treat? If I started kicking him around and tossing him away when he nuzzled my feet, over and over, would he still be attached to me? No, he would learn that humans are bad, and be gone when he saw one. Take the complex facets of human love though. A mother will sometimes love er son or daugher even after they have been proven to have committed a serious crime. Yet does the person's dog have the ability to reasno and know that their owner, say, is an arsonist? No.. it is different and based on the animal's capacity of intelligence (a dog is, say, more intelligent and reasonable than a slug; more evolved..)
