My partner has lived in China for 2 years, and I can assure you many people who live in China are also buying automatic cat feeders and in fact the domestic market is their primary one.
The cat feeder is I understand a feels like a good point as it feels rather trivial, but for the most part technology helps everyone to be more efficient. Even with the cat feeder its not just a few minutes - it means I can stay out later from work, or go on trips for several days without having to worry, or pay someone to come as a cat sitter. Its cost of $50 pays for itself in just one 7 day trip of not paying for a cat sitter, which usually would be some low paid immigrant from East Asia. Efficiency gains all around.
