I just checked in quickly before leaving work for the day and it appears
it is recipe time. I found a site with some great recipes and it
includes recipes for pets so I'm posting one I found that would work for
the Mouser voyage:

Kitty Cookies

1 cup whole wheat flour
1 (6 ounce) can tuna in oil, undrained
1 tablespoon vegetable oil or bacon grease
1 egg

Combine all ingredients; mix well; add small amounts of water if mixture
is too thick. Turn dough onto a lightly floured surface and roll out to
1/4-inch thick. Cut shapes with a cookie cutter and place 1 inch apart
on an ungreased cookie sheet. Bake at 350 degrees F for 20 minutes, or
until firm. Allow to cool on wire racks.
