Curly-Coated Retrievers can be good with cats, but it often depends on individual temperament and early socialization. Some Curly-Coated Retrievers might have a higher prey drive, making them more inclined to chase smaller animals like cats; others might be more relaxed and friendly. If a Curly-Coated Retriever is introduced to cats at a young age and has positive experiences with them, they are more likely to coexist peacefully.
