Tuna uses remote Telekinesis to provide sustenance.

Yes, it works, but it only works 3 times per day... and then in insufficient quantities. Tuna has mastered the art of Telekinesis.... sometimes standing patiently focused for long periods before he is successful. I sure hope he keeps his mind focused only on food.
(Short Video at bottom to verify his success)

Actually, this device dispenses 1/4 cup increments up to 2 full cups... 1 or 2 or 3 times per day... can set it for times desired. This feeder is the result of Tuna's propensity to overindulge . . . therefore becomes a fat cat.
