Why should animal studies not be used for child psychology?

Actually the reverse is more true. It's been proven that children with psychological problems relate far better to cats, dogs and also dolphins than with humans. Dogs and cats (even dolphins) are now being used to help children relate to the animal, then the psychiatrist has a better chance of relating to the child. Dolphines are known to help children with many psychological problems such as depression, being crippled from various diseases or accidents and children respond well in return.
