Small Chinese hamster seeking a patient new home

This Chinese hamster has lived with us for about six months. It's more slender than a typical hamster, looking somewhat like a small field mouse. When it first arrived, it was very wary, hiding at the slightest sound. However, after some time, it has gradually gotten used to having people around. At night, it slowly explores its cage, checking every corner. Its favorite foods are sunflower seeds and small pieces of carrot. Since we recently got a cat, and the cat is particularly interested in the caged hamster, we decided to find it a safer, quieter environment to avoid stressing it.
