Perhaps your cat (which presumably has a gender) is living in an emotional desert.
Cats have different behaviours, but mine (born feral, now very domestic) greets me in the morning, yells for his breakfast, chomps down a few mouthfuls, hops on my lap for a quick fondle, then resumes his breakfast. Afterwards, more cuddles, some dashing about, then he snoozes in a fixed sequence of spots during the day, interrupting his sleeps to join me for lunch. He comes and yells at me around the time I should be knocking off work.
Try assuming there's more going on emotionally in your cat's head - you might both benefit from it!
The robofeeder has not diminished The Cat's appetite for snacks 24/7, but it did reduce The Cat's stress with its predictable precise delivery of food.
I still restrict its access to the computer, as it had been logging on to KatNet and plotting the overthrow of humanity and having us all stuffed into the KatFud hopper.
Once the automatic cat feeder failed and The Cat had access to all it could eat. Had to take it to the vet to unjam its digestive tract.
