Hi Stephen, the Super Feeder is a very reliable automatic feeder and it can be used with stainless-steel bowl. I'm thinking of to order a Cat Mate product or service (possibly the C50 or even the C3000) for the reason that that is nearly the only readily available manufacturer listed https://finnqxdkp.homewikia.com/11785048/examine_this_report_on_royal_cat_food
