One of my twins has cut his finger messing about with the cat flap, he will be one at the end of this month. I've cleaned it but I was just wondering if there is any reason why I can't put Savlon on it? I can't see any age limits on the tube but I don't have the box or the info sheet and unless I'm looking in the wrong place, the website has no info either. Can you use it on a (almost) one year old?
