This question can be answered in 2 ways.. yes and no. As to the first yes.. as Eden is an image of Heaven.. and that Jesus is seen as a lamb in Heaven.. and the book of Isaiah says ‘the wolf and the lamb will rest together:’ it follows that everything God created will be in Heaven.. the stars, mountain rivers flowers etc…

But the the soul is the principle of life. A dog has a soul, a cat has a soul.. but a individual dog say.. dog owned by Aristotle.. that dog does not have an immortal soul. So when that individual dog dies so does his soul as the dog did not have an immortal soul..

A person has an immortal soul.. so when an individual person dies say this person Mary or Peter there soul which is immoral goes to Heaven.. if they are in a state of Grace.. when the person dies there soul lies on..

So each and every person who has every existed will be in Heaven.. if they died in a state of grace but not every animal will be in Heaven but there will be dogs cats and every animal. So to use the example of Aristotle his wife will be in Heaven but not his dog that sat at his feet.. but a more perfect dog will be there just not the one buried under the tree that died when he was a young man..
