Cat Friends are social relationships formed between cats, often characterized by playful interactions and mutual grooming. These friendships can develop between cats that live together or those that meet in shared environments, such as shelters or outdoor spaces. Cats communicate through body language, vocalizations, and scent marking, which helps them establish bonds. A strong friendship can lead to reduced stress and increased happiness for the cats involved, as they enjoy each other's company and engage in activities like chasing or cuddling.
