I don’t have a source for it, but I recall hearing that yes, their eyes work at a different speed than ours, and that’s part of why cats and dogs are generally not so interested in TV. Unfortunately I don’t know what search terms might be useful here since I don’t know if this has a technical name, but something like “refresh rate” or “fps” might help in the search.
Sometimes my cats will be interested in TV, especially if there are really interesting birds. One cat in particular was very interested in Felix the Cat cartoons.
