SIN 4641 and SIN 4642 are two wooden houses that, due to their small sizes, are perfect for hamsters and other small animals. With a nice appearance, they have the front entrance and they are characterised by a flat roof. Moreover, they are decorated with graceful holes that also facilitate air circulation. Built with respect for the environment, they are part of the SIN series for small animal houses, made using FSC certified wood, that is sourced from forests that are managed correctly and responsibly according to strict environmental, social and economic standards and other controlled sources.
