If by reason you mean use of formal logic, you are probably correct. But your definition of learning would seem to be idiosyncratic, perhaps confined to a population of 1 (yourself). I can't think of any animal that has been well studied that does not demonstrate some ability to learn, even simple worms. Learning simply means that the animal is able to modify its behavior according to its past experience with the environment. Anyone who has observed cats recognizes that they do this quite readily. The abilty to train them to perform tricks is not necessarily a good gauge of learning ability. The main difference between humans and other animals is the number of neurons in the neocortex, which is the programmable part of the brain. In addition, what gives you the idea that cats and dolphins don't communicate? Of course they do. Even ants communicate. Maybe you meant they don't talk or they don't use language. Much of human behavior that we consider quite intelligent does not involve the use of "reasoning", including language.
