Frankie pooped in his house. Sounds like un-important stuff but up to this point he was being very, very good and doing all his business outside of his house. I was beginning to think that Frankie had a sense of his surroundings and would not defecate in his sleeping quarters. He proved me wrong and laid out a whole mess of 'crap' inside his house. I am happy that the design of the house is such that clean-ups are easy. I just open the two front doors and sweep the whole mess outside, and then added fresh straw.
