Why adopt an adult cat in Boise
An adult cat's personality is fully formed, so the rescue can tell you how they are with people, other pets and busy households. Many have lived in foster homes and are used to family life.
Grown cats are calmer and need less supervision than kittens, which suits people who work long hours or have young children.
