I'm one of the few my mom's cat Danny gets to see, but I was on his bad side for about two weeks. He was near the front door and didn't move when I went to look out the window on the door. I ended up stepping on him and he screamed like crazy. I felt pretty bad about it, but I could tell he held the grudge longer than my old dog Zelda would when she'd get mad. But eventually, he came to forgive me.
