Since we are talking cats here, let me plug my CatBench vector search playground app, intended to learn and demonstrate in a visual way how (PyTorch + ViT) image embeddings and (Postgres) vector search work together with your regular OLTP transactional data. I implemented a toy version of a purchase recommendation system based on “cat customer” image similarity and “cat fraud detection” building block too:

Also, a simple browser-only page for visually demonstrating what embeddings/vectors physically are, for explaining this to database & storage folks:
