@dan In this paper, we present Cat eXpress Link (CXL), a system for sending Dan a mild shock when the food bowls are likely to be empty in the next hour. In recent feline trials, we found this to improve cat satisfaction by 47% ± 5% (p-value 0.005), n=4. We measured satisfaction scores using cat-attached microphones and machine learning to measure the ratio of meowing noises to satisfied purring events (SPEs.)
