Animal: Auto-calculate and display current age

Enhancement request: Auto-calculate and display the current age of the animal, based on the date entered in the Birthdate field. The age field is then automatically updated by the system and always displays the current age of the animal.This will allow the user to quickly determine the age of the animal without having to calculate it in their head using the Birthdate field.

This feature is implemented in PetPoint. If there is interest in this feature I would be happy to send a screenshot of how this field looks in PetPoint.
