Looking for a quiet, female British Shorthair cat for adoption.

We adopted this cat about two and a half years ago, but unfortunately, due to an allergy problem within the family, we now need to find her a new home. She's incredibly calm, doesn't bother anyone in the house, and often prefers to sleep by the window or behind the sofa. As is known, British Shorthairs tend to have a slightly slower pace, and this cat shares that trait. She's playful but not overly active. When guests come over, she usually observes them from a distance first, then approaches them once she gets used to them. She's not picky about food, eats dry food, and has been regularly checked by a vet. Therefore, we'd prefer to give her to a family who can care for her in a loving home environment.
