There are cases of feral children that have shown, rather nearly confirmed, presence of feelings and thorough bred communication between two animals of the same specie, or inter-specie as well. Fire warning, presence of tiger etc.
Remember, 90% of what we talk ain't coming out of our mouth. Similarly in case of animals, body language has a major role.
For example, a woman named Oksana Malaya was raised by a pack of dogs, so she is said to have grown up as a dog. She is said to easily communicate and behave with/like dogs and communicate in a rather native way - a phenomena they call 'Mowgli Syndrome'.

Check out http://en.wikipedia.org/wiki/Oxana_Malaya and a couple of other cases too. Very fascinating subject, indeed.
