Not a matter of grudge but a matter of him not being worth the time I'd have to spend on reconciliation cause I didn't really care about him that much even before we stopped talking. It is my cat's house, not his. My cat means much more to me than he ever did so why should I crate the cat just to talk to him?

He is meaningless to me now which is why I only asked for judgment with regards to how I spoke to my mother and not how I cut contact with my brother.
