I have a pet cat. I've had him for about 2 years now. Here are some things I've observed in him:
1. He knows how to communicate to humans what he wants. My cat drinks out of the sink faucet. When he wants a drink, he will walk into my view, look directly at me, and meow. Then I get up and walk over towards him, and he leads me to the sink faucet. He'll jump up onto the counter and put his head near the faucet.
When he wants to go outside, he will go to the door, look at me and then the doorknob, and then he will meow.
2. He gets bored, and wants to do things. If I force my cat to stay inside (I don't like letting him out at night), he will continue to meow for about 10-15 minutes at the door until giving up.
My cat likes to have fun. He likes being chased around the house and running around, climbing up trees. Also, he likes when I hide behind something and then jump out and suprise him (at which point he sprints away).
So in a way you can compare him to a human todler.
3. He can feel pride. My cat seems to love showing me how good he is at climbing up trees. Also, when he kills or injures a bird he brings it to the back door, as if showing me his accomplishment.
The point is, I see many similarites between humans and animals in some aspects.
Do Christians believe animals have souls?
