I&#x27;ve envisioned something similar, but for wet food (dry food is better for our convenience than it is for cat health in my experience).  You&#x27;d fill a (washable and refrigerated) cylinder with wet food, which would be forced out a heated tip by a piston (sort of like squeezing a toothpaste tube).<p>The refrigeration and heated tip are the complicating factors.  The heated tip is used because cats don&#x27;t tend to like cold food, and if you&#x27;re going to go to the trouble of hacking something like this together, you might as well go all the way.
