Well I think I found the sweet spot for Caesar's food *knocks on wood*. Looking at him tonight and I still see a little lump from the large rat. So it seems a large rat lasts him about 3-4 days. He is more active though tonight and playing under the paper towels and shoved his acurite around some. Hopefully I can get 2 more days of quietness out of him on that rat lol. And I'll half fill a 20 oz water bottle for him to have a 'toy'.
