Wacky Puppy Water
Pets International
3323 South Main Street
Buffalo NY 14077

Dear Pets International Representative:

 I am a student at Eastchester Middle School in New York State.  My science
class is currently working on the metric system and we have been asked to take a
close look at consumer packaging.  Your company's large Wacky Puppy Water states
that the size is 750 ML.  That would mean that the volume of water is 750 million
liters.  Since this bottle is smaller than a liter of soda, it leads me to think
the volume is 750 milliliters, which can be indicated as 750 mL or 750 ml.

 Thank you for your time and I hope you consider my suggestion.  I look
forward to hearing from you.

 Truly yours,

 Julie Ann Hugick
