* What animals are you talking about? Specific species, animals in a particular location, or all animals in general?
* What kind of event are you referring to? Are you talking about a natural disaster, a human-caused event, or something else?
For example, if you are asking about what happens to animals in a forest fire, I can give you information about how they react to the fire, how they might be affected by the smoke and heat, and how they might migrate or find shelter.
Please give me more details, and I'll be happy to help you understand!
