Nicole, your mission statement does these things:
It states who your audience is: pet owners. That's a huge and very diverse market, because there are many countries with pet-friendly people and enough disposable income to be able to purchase your product, if the price is low enough.
Demonstrates that your mission is appropriate for the world we live in. We have recently seen heartbreaking scenes of abandonded animals in New Orleans and more recently in Houston, and there is no reason to expect the trend for severe weather to abate.
Explains the human dimension that makes the idea compelling and worth the effort to produce. From reading your Mission Statement, we are ready to believe that your product will not be just another object to consume and then discard.
