The perfect diet.....

Watching barn cats look after kittens taught me a few things about "small cat nutrition".  The mother tirelessly hunts to feed her family.  She brings them

protein

in the form of birds, mice, gophers and pocket gophers. 
I really don't like rodents and I'm not good at catching them, so I fed him the next best thing:

hamburger!

On a cattle ranch, ground beef is readily available. 
Three or four times a day, Little Scruffy gobbled up a small hamburger covered in milk.  Autumn also loved the hamburger mixture, and had finally given up on trying to eat the little guy.  In her eyes, he was no longer a mouse.
