Why is overproduction a problem?
some species are hard to place due to their size
What are some birth control methods in the zoo?
- keep sexes apart

- OVH females
- hormone implants in females

- delivery media (charge)
- tail piece
Why should we give an animal antibiotics after shooting it with a dart?
because the dart is not sterile
Why do we need to fill the syringe all the way before using it in a dart?
because if there is air in the syringe then it will get into the animal
