Help! I am a new (first time) cat owner and our new kitten has decided that using the litter box is optional. She likes to urinate and defecate right behind the bed (not so accessable for cleaning!). When we first got her she used the box everytime and was good as gold. But this new problem started a little under a week ago (we got her Nov. 11 and she's 14 weeks old). We're using wood pellets as litter (as recommended by the breeder) and I've changed the litter twice (the problem started just after I changed the box the first time - coincidence?). We scoop any poop immediately. We've tried pepper behind the bed to try and dissuade her but I just found a fresh poop back there so while she doesn't like the smell, it doesn't stop her. My hubby and I are going nuts with this. We could understand if she was doing this from the beginning and as we haven't changed anything since we got her we can't figure this out. We live in a one floor condo, her box is in the master bathroom which we make sure she always has access to. The bathroom is large but we don't want to confine her to it as we feel guilty. She gets positively reinforced with treats when she uses the box. She's good as gold about everything else. Any suggestions/advice would be most appreciated. We're desperate to stop this.
