Praise the Lord

I was thinking about the phrase, "Let Everything That Has Breath Praise The Lord." God actually commands all His creatures alike to praise Him. David wrote about praising the Lord in Psalm 150:

Praise the LORD.^a

Praise God in his sanctuary;

praise him in his mighty heavens.

2Praise him for his acts of power;

praise him for his surpassing greatness.

3Praise him with the sounding of the trumpet,

praise him with the harp and lyre,

4praise him with tambourine and dancing,

praise him with the strings and flute,

5praise him with the clash of cymbals,

praise him with resounding cymbals.

6Let everything that has breath praise the LORD.

Praise the LORD. (Psalm 150:1-6)

 I've been thinking a lot about animals, and how they should be treated. I looked up vegetarianism in the Bible, and to my surprise, God actually created the plants and the fruits in Genesis for food, and then God gave animals to keep men company, that we may live in harmony with each other. I read forward, and read that Jesus was a vegetarian. Some scholars have researched that the "fish" Jesus gave to the 5,000 with the loaves of bread, was originally translated to mean "fish weed," or seaweed. The greek word for fish ichthys, which in English means "Jesus fish."
Jesus as the perfect of example to kindness to people, and animals. If becoming vegetarian to me, means that I can give back to what God has given to me, then may He be glorified!
Furthermore, I realize that when God said, "Let everything that has breath praise the Lord," he meant animals, too! Is that why the birds sing during the day, or the wolves howl to the moon at night? They are praising the Lord? This, to me, is beautiful.
