I have 2 cats, Bunion (age 7)and Furlough (age 5). Bunion had the run of the house his first 2 years. then I got Furlough. They learned to tolerate each other, but there is no love lost between them!! They occasionally hiss and swipe at each other but nothing major. Yesterday, I had them out on the porch, and Furlough spotted a stray cat on the grass. Fearing that they would try to jump the railing, I picked them up and quickly put them inside, next to each other. Next thing I know they are hissing loudly at each other, and start to fight. I quickly separated them, almost getting bit myself, and kept them separate for about an hour. When back in the same room, they immediately start fighting again. I tried this 2 more times (at longer intervals), with the same results, fighting and hissing. That night I put Furlough in the cats room and let Bunion have the run of the house, hoping that things would be different in the morning!! No such luck, Bunion wouldn't even eat in the same room (and Bunion loves to eat!!). I decided to let both of them have the house, instead of separating them, hoping that with a little time they would be better. They are constantly hissing at each other when anywhere near the other. Is there something that I should be doing differently, or should I just hope that in time they will get back to how they were??? Any advice would be appreciated. Bets
