Were there animals in the garden of Eden apart from the snake that Satan used as his tool?
On the sixth day, prior to Eve being created, we are told:
"Out of the ground the LORD God formed every beast of the field and every bird of the sky, and brought them to the man to see what he would call them; and whatever the man called a living creature, that was its name. The man gave names to all the cattle, and to the birds of the sky, and to every beast of the field, but for Adam there was not found a helper suitable for him" (Genesis 2:19-20).
Therefore, all the major kinds of animals were in the garden with Adam, at least briefly.
