Hello and thank you for reading my post. I have a 4 year old Persian cat that has suddenly become afraid of the room he uses for his food water and litterbox. He has used this room since I adopted him about 6 months ago but now is afraid to go in there. I tried to carry him into the room and he hissed when i tried to put him down on the floor and he ran out of the room. He will not go in there to eat drink or use the litterbox. I had to move his bowls and litterbox into the living room where he seems most relaxed. Nothing has changed in the house except we put up the Christmas tree but that is in the living room not the room he used. The only thing in the room he used is some boxes and my computer desk and computer. He is eating and drinking like normal. any ideas?
