When we decide to take in a new type of animal, we always consider veterinarian bills. Can we afford it?If we can't, there's no reason to take in pigs or cows.
That's one reason we don't have more livestock, but as for now we could afford it, but we wish to move closer to the ocean to be able to catch fish without having to drive to get there.
But always always consider the bills before you buy livestock. It's our most important job if we own animals: to take good care of them.
