Clinic trick for speed eaters is predictability plus tiny portions... Aim for four to six hours of coverage during your busy window and then a couple of small overnight drops. For most adult cats that ends up around 8 to that model events, each one eighth cup or less with slow feed on. Keep the first week identical so his gut and brain settle. Expect louder meowing the first few days. Then it fades.
If vomit happens, do not add volume at the next meal. Shorten the interval instead. A two minute trickle works better than a dump. Place the unit on a grippy mat and angle the bowl slightly by propping the back feet so kibble rolls inward rather than popping out. Uniform round or small triangular kibble jams less. Anything big, oily, or powdery increases clogs. Wipe dust out when you refill and toss in a fresh desiccant to cut static.
