Ferrets love a cosy, enclosed hideout to burrow into and sleep, and since they nap for much of the day, a snug bed or cave is a much-loved comfort. The best are soft, roomy enough for a ferret or two, machine-washable, and free of loose threads. We compared ferret hideouts on softness, size, washability and safety, so your ferret has a secure, cosy place to curl up.
