i don't know if this is the place to put this but here goes my question. I have two cats a male and a female both fixed. lately there has been this other stray cat hanging outside of the apt. Yesterday morning i woke up and walked in the kitchen and it smelled of cat spray. This morning i wake up and the scent was in the kitchen, bathroom, hallway and my bedroom. all places where there is a window. The only place the smell was not in was my brothers bedroom. i tried to smell around my room in areas my babies sleep or hang out in but could not track down the odor. I lit an incense which seemed to make the odor go away. Could it be that the other cat is spraying aroudn the outside of my apt and the scent is coming in. or that one of my cats is doing it. And how would i be able to find where they are doing it. I have had one cat for over a year and the other for about 4 months, and never had this problem.
