Princess Pea is a 9- or 10-month-old cat who was found out on the street by some college students who just couldn’t afford her vet care. She’s been spayed and vaccinated, and she’s all ready for a home–she’s very sweet and mellow!

Petal came into the shelter’s care very pregnant and had 5 beautiful babies. She’s very sweet and active, and greets everyone as if they are an old friend. She is about a year and a half old.
