We all have souls. Animals have souls too.

Ecclesiastes 3:19-21 ESV
For what happens to the children of man and what happens to the beasts is the same; as one dies, so dies the other. They all have the same breath, and man has no advantage over the beasts, for all is vanity. All go to one place. All are from the dust, and to dust all return. Who knows whether the spirit of man goes upward and the spirit of the beast goes down into the earth?

Romans 8:9 For the anxious longing of the creation waits eagerly for the revealing of the sons of God.
20 For the creation was subjected to futility, not willingly, but because of Him who subjected it, in hope
21 that the creation itself also will be set free from its slavery to corruption into the freedom of the glory of the children of God.
22 For we know that the whole creation groans and suffers the pains of childbirth together * until now. 

I think animals will go to heaven. They did not sin.
