Stickied here and also copied into our DIY forum. Nice job Mike! I'll definitely be making some of these as soon as I phone Home Depot and make sure they stock those metal zip ties.
I'm thinking I'll use these for the lab blocks and still offer a bowl of mixed seed and cat kibble every few days just as a suppliment to the lab block hopper feed. That way I get the best of both worlds and the ASF's can have a bit of variety in their diet. Should definitely save me some on my monthly feed costs for them.
