I don’t know how to make her feel better, my sister’s cat is 16, Muki is her name, my sister had her as a best friend and confident growing up, she was a lonely kid and Muki was her everything, she made a tiktok to document her diagnosis and last days, to help her cope, I really don’t know how to help her

Her account is “uncachitodetiempo” that means a bit of time, is clear that she is feeling absolutely devastated and I know (I lost my childhood dog at her age too) that dealing with loss is part of life but I wish I had a form to help her… Could you help me with some words that did made you feel better when you lost a best friend cat? Thank you.
