I would also exclude domesticated animals where the questions deal with the exploitation for commercial or other purposes. As an example, a question on how to get rabbits to the highest weight at 6 to 8 weeks of age implies non-pet centered motivation. Assuming there is no forth coming clarification bringing it into scope it should be closed and deleted. While questions about healthy steps to increase or maintain weight in rabbits (i.e. How can I help my adult rabbit gain weight? ) is in scope.
The type of animal is not important, it is the relationship that makes an animal a pet. Pretty much every domesticated animal (except maybe cats) have and (depending on culture) do fill dual roles as both companion (pet) and food source.
