Today, when Yuchi (new spelling) came for breakfast I fed and petted her, then came inside to get Salvador, who was watching anxiously out the kitchen window.
I put his harness and leash on him and he scooted out the door to sit on the porch and watch her from 15 feet away. She rolled around on the ground in the sun and kept an eye on the big guy sitting on the porch.
After a few minutes he walked down the stairs toward her. She held her ground but came to her feet and faced him. They looked at each other, but there was no aggression from either. They chattered to each other, then strained forward and touched noises.
She raised one paw and hissed softly. He hissed back, but very softly. She turned, walked a few feet away and lay down. He lay down and watched her for a few minutes. Then he got up and moved closer to her. She moved away and he followed. They played cat and cat for 15 minutes. If he moved she followed, if she moved he followed.
I had to drag him back by force. I don't think it will be too long before they're friends.
