Rehoming a sweet, shy 4-year old cat

Hello, I am looking to rehome a small, 4-year-old female rescue cat. I am now retired and would like to begin travelling with less responsibility for the time being. Mi, my cat's name, is shy at first, but very sweet, and will nussle up in bed for petting and purring, etc. Mi has all her shots. Highly reputable, responsible inquiries only. I will check references to ensure Mi is safely rehomed. (Mi is the kitty on the right in the attached photo.)
