Hi guys, Any help would be gratefully received. Research is sending us in circles. We are just designing our meerkat enclosure but we are struggling with what to use as the base; If we use concrete we are worried about drainage! If we use mesh, will it last? What is the best substrate? We are thinking sand/fine gravel (and to fill burrows in daily). Many thanks in advance. Any other guidance relating to meerkats would be fantastic!
