I also prefer gripe water, purely on the basis that when I gave Dudley infacol last year, I found maggots in the litter tray even though I was cleaning it twice a day :shock: it wasn't even that hot and it was the overnight tray, I had never seen that before and I can only assume that infacol makes the poo irresistible to flies. So as there is an alternative, I prefer to reduce the risk that way!
