Which pet will be produced for the children?

The robonannies have produced chickens and goats to provide eggs, meat, milk and entertainment for the children they are growing.

A brother suggested rabbits because they have several offspring so can provide plenty of meat and entertainment in a short time naturally.

The rabbits would be difficult to eat if one day they are cuddly and the next casserole.

So what pet should be grown by the robonannies?

Suggestions appreciated.
