You Have a Friend in Me

 Be it a frog

 Or lots of times a dog

 And more times than that, add a cat

 Her love for them is as great as their love for her

 She shares her favorite seat.

 And plays games so neat.

 Sometimes she might invite a human friend

 And for a cuddly hug she'll always bend.

 Even slippery fish

 deserve a kiss.

 And baby birds

 Or tiny chicks

 Easy does it, does the trick.

 The look on her face.

 The sparkle in her eye

As she loves and rocks them by lullaby.

A mouse in a bus 

 Riding in the bouncy seat is a must.

 Down low or up above,

 She'll go to great heights to show them her love.

 She chases, loves on, hugs, kisses, and probably drives them a little wild.

But animals make great friends when you're an only child :)
