Babies, like all humans, are made in the image of God, in addition to being ignorant. Animals are not made in the image of God.
‘Hmm, I do not have enough money. You have lots of money. I kill you. I take your money. Now I have lots of money. That was not murder, I was just killing to survive.’
That argument doesn’t hold water. Also, are you trying to bring animals up to our level or humans down to an animal’s level. If, like @Julie_Martin said, animals could talk before th fall and go to Heaven, what is the difference between us and animals and if you say because God chose us to be special I might as well be a radical racist towards other races because I might consider my race more special than your race.
