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.

Well, I’ve never particularly cared for sports, either, so this improved my opinion of exactly nobody.

Thank you for indirectly leading me to discover the book title “The Frugal Wizard’s Handbook for Surviving Medieval England”. Even if I never work my way to finding out anything further about this corner of literature, that title certainly tickled me.
