I have a funny story...When I rescued Patches and her brother and sister, they were about 5 weeks old. I made a nursery for them in the powder room downstairs by the front door. When I would let them out for a bit (maybe 30 minutes) to explore, they would run to my cats if they happened to in the living room. My cats would take one look and run the opposite way.
One day Bounder, I think, was caught unawares. He came downstairs and strolled into the living room and stopped in mid stride when he saw the kittens -- they hadn't seen him yet. He turned around and went right back upstairs.
We found homes for the other two kittens and kept Patches. She adored Bounder. Once they were upstairs and Patches ran to Bounder and tried to tackle him. He just stood there with her hanging around his neck. I wish that I had gotten pictures because Bounder began to walk off with Patches still hanging around his neck!!!
