Aww... I get that they need to graze... so if that's the reason, please consider freezing your own wet food pucks. I used a couple tupperware 2 oz cups to do mine, others use icecube trays. Mixing a bit of water in and then freezing... then putting the pucks in a container or baggy in the freezer makes it easy to take out one or two at a time.
I used to put one frozen puck under the fresh breakfast and then Sundance could eat it as it thawed through the day. Many people use that method for their FD and civvie kitties so that they can graze.
Remember though, cats don't need to graze.. they are fine with meals if they get what they need at that time. Unless there is a health issue that dictates that they eat several small meals a day.
If funds are an issue, there are inexpensive low carb foods that are better than dry too. I know it sounds like a lecture of sorts, but really, so many of us ended up here because of dry food, I'd hate to see you switch them back to dry and end up with one or more becoming diabetic or having other issues due to food.
Good luck... if you try the frozen route, let us know how it works out.
