Respectfully disagree, The Cat in the Hat is really showing it's age and I don't think it's something that random refurbs to keep it up and running is going to fix. Unless they completely revamped it with all new animatronics and a better track (which doesn't seem worth the investment/time to shut down the one and only dark ride they have/the money to invest in an old IP) it's not good. IOA needs a dark ride that it deserves, not one that they just keep running because it's there.
Edit: Sure, Pets and Cat in the Hat might both be "all age" but I don't think you can really fairly compare hem because Pets is also brand new and running smoothly, whereas Cat in the Hat looks like the stuff of nightmares these days.
