My Chuck (F4 3 year old) just today decided he would urinate outside of the litter box. He has been problem free for litter habits since day one. Just today he has been scratching in weird and random locations around the house and trying to urinate...tonight we caught him trying to poop in the wrong spot so I plopped him in his box and he pooped there...He doesn't appear to be drinking his usually large amounts of water. Today was a bad day for stress as the kids didn't sleep well and were at screaming and anger stations pretty much all day...I hope this is just a passing "thing" and not anything serious. Anyone have this issue? advice?
