FR7

 Today Catnip attempted fixed ratio schedule 7. She was feisty when I put her into the cage and began to press the lever right away. Catnip responded a total of 649 times! She began to pull on the lever again today and was irritated when she did not get pellets fast enough for her liking. She would bite on the bar and get under it in an attempt to pull it. I believe this was due to the drop in the grams of food I had given her. She took only 1 small break to groom but still continued to push the lever even after she was done.
