Let me give you the back story. I have a 6 year old male cat (who has never been fixed). He is the only cat that we have. In our house we keep two of the three rooms closed off and just use them for storage. I will open one of the rooms on a daily basis because that is where I keep my clothes. Midnight (my furbaby) will run in to investigate and he has sprayed in there. Now everyday he yowls and yowls to get into that room. I have given up before and just let him in but of course he sprays again and starts yowling again. We have a new baby coming and I will be using that room more often and will have to leave the door open. What should/can we do to stop his yowling and spraying? I have attempted to put a litter box in there but it had not effect. I'd like to rip up the carpet but we won't be able to do that until after the baby comes. He has sprayed in our bedroom but stopped when we put out more litter boxes. The last resort would be to get him fixed, but really see no need since he's or only cat. Any suggestions on what to do? Should I leave the door open all the time?
