keeps shitting outside my girls bedroom door in the night or early morning. she is nearly 9 months old, not had her first season yet (as far as i know) and is unspayed. (being done after christmas) litter tray is clean, but downstairs and has been in same place for ages. she uses it for most of the day, its almost like she cant be bothered to go down two flights of stairs to use it so shits half way down.
