Beat butter, white sugar, brown sugar, eggs, vanilla extract and pumpkin together in a large bowl with mixer. In another bowl combine flour, baking soda, cinnamon, salt, nutmeg and oats. Mix well with wire whisk or spoon. Combine flour mixture with egg mixture mixing well. Fold in butterscotch chips.

Drop by tablespoons on ungreased cookie sheet. ( I just roll the dough into balls about the size of a walnut with my hand and flatten on cookie sheet to the size cookie I want.) These cookies will not spread on the sheet.

Bake in preheated 375 degree oven for 10 to 12 minutes.
