Chocolate Chess Pie

From Family Recipes:

9 inch unbaked pie crust
1 1/2 c. sugar
3 Tbsp cocoa
1 stick butter, melted
2 eggs
1 small can pet milk
1 tsp vanilla
dash of salt
1 c. broken pecans

Pour melted butter into blender. Add all ingredients, except pecans, and blend well. Stir in pecans, or add just to top. Pour into pie crust. Bake at 350 degrees for 50 minutes.

What in the world is pet milk? I sure hope it doesn't come from cats or dogs!?
