A device for preventing or reducing emittance of odors from moisture-absorbent material to the environment whereby the moisture-absorbent material is intended for receiving animal excrements and urine. The device comprises an air stream generator which penetrates air streams through the moisture-absorbent material, and a bottom for supporting the moisture-absorbent material, the bottom having apertures through which air streams from the air stream generator pass before or after passing through the moisture-absorbent material. |
