Louise the lab rat, 
Louise the lab rat, 
There's nothing as adorkable as 
Louise the labrat

She coud hide in your pocket, 
Or sleep on your lap, 
She can hide on your head 
whilst avoiding your cat.

If the cat jumps up, 
or goes for a bite 
She'll bop its ears 
and wont go down with no fight

Louise the lab rat, 
Louise the lab rat, 
If you had a cheese sandwich, 
She eat it as a snack.
