There are more lost pets after earthquakes, and the fourth of July, but I would be hard to convince that the number of runaway of lost pets is correlated with earthquakes and useful for predictions of future earthquakes.
The theory that you are investigating has been advanced before and subjected to statisical review, using the lost-and-found ads for pets in the San Francisco Bay area. The study is summparized at

You can find another "science fair" investigation of this theory at

You find the method and results interesting, and easy to follow.
