Just moved so we are making a new bunny room and had the idea of using 3/4 inch rubber mats in one area of the room for litter boxes/ food and hay for easier clean up. Has anyone used rubber mats? We thought they'd be less slippery than coroplast since we have a bunny that doesn't like slippery surfaces. However the ones that we purchased have a rubber tire smell so we are now worried about toxicity. Has anyone else used rubber with good results? I can't find much when I google it.
