Animals are persons

Yes, which makes Ohio full of cannibals!

I think animals have goals because you see cat hunting mouse with a clear goal of either eating it or playing with it.

Cats also know how to ask for things from humans or other cats when they are hungry or have some other need.

This is basically same as in humans.

There are plenty of similarities between humans and animals: pain, happiness, sentience, goals... I wont use only one.

Animals feel pain, happiness, and they may face the other two, I just haven’t learned that much.

I can make it standard if someone wants.

There are plenty of similarities between humans and animals: pain, happiness, sentience, goals... I wont use only one.

But there are also differences which dont logically justify significantly different treatment, such as intelligence, techological development, abilities...

If that’s your definition, you might want to use either sentience or intelligence?

I am not really sure how to define it. If I define it as beings deserving moral consideration,

what will Con argue? Sadly, often the only way to get people to accept is to give them advantage.

I cant think of a balanced definition for "persons" here. Basically, it either favors Pro or Con, not both.

You probably already know this but this is going to go horribly if you don’t define “persons”.
