Help with some christian beliefs (about heaven)?

Nowhere does Scripture explicitly state that animals do not have souls...There is nothing in Scripture I know of that would preclude the possibility of animals' continued existence...The Bible does give us some reason to hope that departed animals will be restored. We read in the Bible that redemption is a cosmic matter. The whole creation is destined to be redeemed through the work of Christ (Romans 8:21), and we see the images of what heaven will be like; beautiful pages of Scripture tell us about the lion and lamb and other animals being at peace with one another.(Isaiah 11:6-8). Whenever heaven is described, though it may be in highly imaginative language, it is a place where animals seem to be present. Whether these are animals newly created for the new heavens and the new earth, or they are the redeemed souls of our pets that have perished, we can't know for sure.
