How long should I wait to get another kitten? Does it dishonor my cat that just died if I get one so soon? I miss her terribly, and know I will never replace her, but I miss the companionship.

My 19 year old cat just died last night. I have spent half of my life with her. Now I am missing her company so so much. Is it a bad idea to get another cat so soon? I know I could save one from euthinisation now. I want my old cat back, but I know that won’t happen. Should I wait? I hope I can luck out and get another healthy and loving cat like she was. Everyone who ever met her loved her, even those who didn’t like other cats. What should I do? Wait six months or a year? I miss my friend.
