Everything I Hear

Everything I hear I say to others around.I’m not an animal, nor part of the human race.I will, immediately, repeat after you;But only if my tails in place.

Small I Am

Though small I am, yet, when entire,I’ve force to set the world on fire.Take off a letter and it’s clearMy paunch will hold a herd of deer:Dismiss another, and you will findI once contained all humankind.
