Should we have a biology, anatomy or physiology type tag?
To give a few examples:
The answer to this is concerned with the rabbits physiology:
Do bunnies eat their droppings?
The asnwers to these are concerned with the animals anatomy:
Why do cats often screech when mating?
Why do my dogs stand back to back when they mate?
Should we have a biology to cover actual physiological or anatomical facts about pets?
