Why do I feel so guilty now my cat has died?

hey, im really sorry about your cat. i have to cats. there not abused or anything there always fed but both of them have something wrong with them and they might die :'(, so in some way im more prepared but i no how you feel, i know what u mean by you have the best cat in the world because one of the two cats is mine and the others is my bro and the other one absolutely adores me and i love it and i don't want to live my life with out it, your not being silly at all but i think if you got another cat it would be better maybe a good reminder for you cat to live with you through in a way just make sure you choose a cat with the same characteristics or idk personality as your cat. you have no reason to feel guilty at all his/her death wasn't your fault and you can tell by the way it acted it loved you so you can grieve but don't feel guilty and don't loose sleep, its okay <3 i do surgest what i said about another cat and i truly am really sorry (:
