I hope things will go well when you bring the new cat home. I am so sorry about Malachi. I had a similar situation when my cat developed a sudden tumor and the vet didn't give a good prognosis for recovery if I proceeded with surgery. I am always wondering what I missed symptom wise. Malachi knows you did the best you could for him and he remembers your love. You are honoring his memory by giving another cat a good home. Best of luck with your new cat and may you always have warm memories of dear Malachi. Malachi is always with you in spirit.
