This is Peanut Butter, a 9 year-old calico who has lived with me for the past two years.
She is the most loving cat I have ever encountered, curling up to me all night and sitting on my lap whenever possible. She was left at a shelter because she had bladder stones which the shelter vet was able to cure.
Because she is on a special diet, she was designated a "special needs" cat and waited a long time for someone to see beyond this tiny problem.
