there is still no proof that animals can really talk and have a conversation

This is a really good article :) I think it's also important to understand that we can't humanise animal emotions and thought processes. I read a great article a while ago explaining that our emotions are quite unique to humans.

Happy, sad, anxious, scares, pleased etc... there's no reason to assume animals have these exact emotions. We know emotions are very complex (happy vs excited or sad vs devistated) and are both situation and person specific. There's no reason to assume they're not also species specific!
