What did they do with the animals?

Please provide me with more context! I need to know what "they" refers to and what animals you are asking about. For example:

* "What did they do with the animals at the zoo after the fire?"

* "What did the researchers do with the animals after the experiment?"

* "What did the farmers do with the animals after the drought?"

Once I have more information, I can help you find the answer.
