These are a couple characters I have been working on for quite some time. Marigold the Brown Swiss cow and Emmett the mountain lion.

Emmett works as a farmhand on Atlas' farm and helps take care of daily chores. One of his duties is to milk Marigold.

Marigold was very small when she was born but through the use of (and possible overdose of) bovine growth hormones. Marigold grew and Grew and GREW.
Becoming quite the massive bovine.

Though even to this day, Marigold has been known to sneak a bottle of bovine growth hormone while no one is looking.

She can be a bit dominate with Emmett, especially around milking time. ;-)
