name ur pet...!!

There is abundant evidence that horses, dogs, cats and many other animals do, indeed, understand and respond to names. Animals do not have language in the sense that humans do but they are aware of their own individuality and of that of others and can also respond appropriately when we communicate with them in speech. Naming, in any case, may not be a uniquely human activity: there have been studies with dolphins which indicate that they, too, may have names for each other - that is, they make unique sounds when communicating with other individuals.

No.They can understand their name. http://wangtf.edublogs.org/
