my boy was mostly pottytrained. i say mostly b/c he will potty next to his litter box if there is anything in there. the last few months ive been sick, so i was at home most of the time with him. i have recently went back to work so he is confined to the laundry room while im gone. the last couple of days maybe even a week or so i've noticed he's chewing on the door edges and he is using the restroom outside of the litter box

. he also runs from me when i call him like he thinks im going to put him back in the laundry room. i let him out as soon as i get home and he doesnt go back in ther til in the morning. what is going on and what can i do to correct this? i dont spank him when he has accidents or chews but i will fuss at him while im cleaning it up ( since its just me and him i have no one else to fuss at). but i have to correct this before it gets out of hand...im afraid to leave him not locked up while im gone b/c i think he will potty all over the house. the point is when should i let him wonder without ever being confined again? can someone please tell me what im doing wrong? i love him to death but am very frustrated
