So about 13 months ago I moved to new house and decided to adopt a cat outside my old house named Johnny that I took care of for about a year. He used to come in out of my house. He is now about 2 years old. I have two other cats too, one 13 years old and the other one about 11 years old. I did the slow introduction in the new house and my 11 year old does not care for him but shows Johnny if he does not want to messed with, but my 13 year old one named Oscar is scared of him. He stays in some area of the house and when he walks around he looks around him because he is afraid of Johnny will chase him. Johnny knows that and he intimidates him. I keep Johnny in the garage at night otherwise things are not going to go well! My older cat Oscar likes to go to second bathroom and sleep in the upper shelve of the closet but the last few weeks he is peeing pooping in the floor there. He looks like he is scared to go tho the room with litter boxes that I have had since I moved to new house.( he does not have any medical issues and he did the same thing while back in my other bathroom but now I closed the door) This is been going on for a year and it is not getting any better. Johnny is always looks like he is looking for trouble. They don’t like each other. I can’t keep him in the garage all the time because it is just not right or lock him in the room. I am running out of options. I am thinking about have him in and out of the house. He is used to outdoor in the new house and it is pretty safe. Any suggestion or ideas will be appreciated.
