New collar?!?

Mom told me today in a most reassuring voice that she was looking for a nice safety collar for me, but that she would take the bell off so it wouldn't drive me insane. My question is, why does she think I want or even need a collar. I have no desire to go outside, and I'll even cross my heart and promise not to go out. I guess she forgets that we tried that whole collar thing when I was a kitten and we decided as a family to not do the "collar thing."
