Why should we be kind to animals/pets?
Here's the answer:
God made animals, and He wants us to take care of all His creation.
If you have a pet, your pet is probably a real friend to you. Maybe you like cuddling with your cat when you’re feeling sad. Or your dog comes to meet you at the school bus stop every day. Pets can make you feel loved and valued. So it’s often a joy to be kind to them.
Since God created our pets and all other animals (Genesis 2:19–20), He would want us to give them the best care we can and always be kind to them. When we do that, we’re really being God’s servants to them. In fact, Proverbs 12:10 teaches that "Those who do what is right take good care of their animals." A believer in Jesus, then, should take good care of his or her pet and be kind to any animal, large or small. All are creatures of our loving God!
"Then God said, 'Let us make man in our likeness. Let them rule over the fish in the waters and the birds of the air. Let them rule over the livestock and over the whole earth. Let them rule over all of the creatures that move along the ground'" (Genesis 1:26).
"The Lord is good to all. He shows deep concern for everything he has made" (Psalm 145:9).
"Aren’t two sparrows sold for only a penny? But not one of them falls to the ground without your Father knowing it" (Matthew 10:29).
