First let me establish that I have always been a dog person, everyone in the family was a dog person. After raising and training sheppards, cats are a new learning experience.
About a 1 1/2 years ago a stray cat showed up on our deck wet and shivering, winter was in its onset, make a long story short we got adopted. She chose a house of german sheppards and a pitbull. How the coyotes didn't get her I haven't figured out. She's wise in the ways of the woods and a better mouser I couldn't wish for. She couldn't trully be feral as she''ll let me handle her anyway I wish - total trust.
Anyway another stray showed up yesterday. She tried to sneak into the barn, got chased out by the present cat, bit, and treed. Well, we got her out of the tree and make a long story short, promptly adopted my wife. She's a very young adult , nothing but fur and bone; starving. Her heart melted (especailly after losing her dog) and I couldn't say no.
The old cat has plenty to say though. Yowl yowl hiss hiss. On advice of a freind we put the new cat in a cage with water, food, litterbox, and bed. We left her in a side room with the door open. The old cat will have nothing to do with the room and hisses evertime she sees the new cat. This is only day two. Are we doing it right? How long will it go on? Any advice?
I always thought the problem would be between cats and dogs, the dogs have no problem with either cat.
