Thank you for writing. We will try to answer your question.
We need to look at God's creation and heavenly intent separately from the condition of the corrupted world as we know it today; for as we are taught in the Bible, the whole of creation will one day be redeemed (Isaiah 11:6-9, Romans 8:18-23, Revelation 42:4).
When we read the creation story (Genesis Chapters 1 and 2), we see that there is no death and that all animals ate only plant foods. After the fall everything became corrupted and humans and other animals began to kill and eat each other.
We hope this helps.
In the Love of the Lord,
Frank and Mary
