This is a little late as I only found out during the 2nd film. Originally the listings for today (17th) were as followed:
(09:00) Tom & Jerry: Robin Hood and his Merry Mouse
(10:10) Top Cat: The Movie
(17:00) Scooby Doo: The Mystery Begins
But instead, the listings have been replaced with Happy Feet and Cats and Dogs. Then, Wednesday will run Willy Wonka and the Chocolate Factory instead of Aloha Scooby Doo, with an extra repeat on Thursday.
(09:00) Happy Feet
(11:00) Cats and Dogs
(17:00) Happy Feet
(09:00) Scooby Doo on Zombie Island
(10:35) Scooby Doo and the Spooky Scarecrow
(16:00) Scooby Doo: Haunted Holidays
(17:00) Big Top Scooby Doo
(18:00) Willy Wonka and the Chocolate Factory
(16:00) Willy Wonka and the Chocolate Factory
Also on the update, another one-off broadcast of Make Shake & Jake will air on Friday 23rd at 21:00.
Also, Apparently Cats and Dogs had previously aired on Friday 16th at 17:30.
