Dear Friend,

Many of you may not be aware that Ainsworth Pet Nutrition has a sister company in the Joplin, Missouri area called Hampshire Pet Products. While plant facilities were not significantly affected by the recent tornado, a number of Ainsworth Pet Nutrition families have been directly impacted by the loss of property and, in some cases, loss of their primary residence. The devastation in the Joplin community has been well documented in the news. It is difficult to comprehend the extent of the impact on property and families in the Joplin community.

To support these families in their efforts to rebuild, Ainsworth will be matching employee donations. However the greater need in the entire Joplin community that affects our families and so many others are also of critical importance to us.

Efforts to help these people and pets are being managed by the local disaster relief efforts of the American Red Cross and the ASPCA, working in conjunction with the Missouri Humane Society. We encourage you to donate what you can to help people and their beloved pet family members in this time of need:

American Red Cross: redcross-ozarks.org
ASPCA/Humane Society: aspca.org

Thank you in advance for your support in this time of need for Ainsworth families and their pets.

Best Regards,

Sean Lang, CEO
Ainsworth Pet Nutrition
