Living like an animal

We work like a horse.
We eat like a pig.
We like to play chicken.
You can get someone's goat.
We can be as slippery as a snake.
We get dog tired.
We can be as quiet as a mouse.
We can be as quick as a cat.
Some of us are as strong as an ox.
People try to buffalo others.
Some are as ugly as a toad.
We can be as gentle as a lamb.
Sometimes we are as happy as a lark.
Some of us drink like a fish.
We can be as proud as a peacock.
A few of us are as hairy as a gorilla.
You can get a frog in your throat.
We can be a lone wolf.
But I'm having a whale of a time!
