Is spaying/neutering animals biblical or is it a sin?

Last month, i emailed Pastor Dr. Charles Stanley to ask whether spaying/neutering animals is biblical or is it a sin?

Today i received the answer:

"We would share with you that there is no mention in Scripture of the concept of spaying and neutering animals. The role of animals as pets (as opposed to animals that helped perform work) was not as prevalent in biblical times as it is today.

We see nothing in the Bible to prevent spaying and neutering of animals, or that would indicate doing so would be a sin. We believe, in many circumstances it can be considered a wise thing to do both for the health and safety of the animal, and for the wise financial stewardship of its owner.

We encourage you to take this matter to the Lord in fervent prayer, reading His Word and praying as King David prayed in Psalm 25:4-5: “Show me Your ways, O Lord, teach me your paths. Guide me in Your truth and teach me, for You are God and my Savior, and my hope is in You all day long” (NIV). God promises: “I will instruct you and teach you in the way which you should go; I will counsel you with My eye upon you” (Ps. 32:8 NASB). “Call to Me, and I will answer you, and I will tell you great and mighty things, which you do not know” (Jer. 33:3 NASB)."
