I have a neighbor that had a one person cat. The cat would do anything for the son but would attack everyone else. I felt bad since this was the first cat they ever had. When it died, they got one more and it was night and day. They finally had a good cat, with personality.
I also had someone drop off 3 cats. One cat was a problem. She attacked all the cats. My nephew finally got a home and I gave him this cat. Worked perfectly. She was a one cat in the house type.
Fletcher is very smart.
He sits and listens as I am talking to him. The pupils of his eyes would dilate at important things. He is a fascinating cat.
He knows the word and the spelling of TREATS. Comes running and then I tell him in the kitchen or the cabinet and he goes there and waits.
The cats that are allowed to go outside knows the word OUTSIDE and they run to the door and they have to touch the door knob before they can go outside.
He does pick on his sister, Dottie
