Willa is a Manx and very small for her estimated age (about 4 yrs). She is very skittish and is not currently doing well in a home that fosters/rescues other cats/kittens. She has behavioral issues with urinating in areas that she's not supposed to if another cat/kitten uses her special litterbox. She doesn't bite or scratch. She does well with dogs that she knows- it's just other cats she tend...
