Trap Happy Porky is a 1945 Warner Bros. Looney Tunes short directed by Chuck Jones and written by Tedd Pierce.
[1] The short was released on February 24, 1945, and features Porky Pig, along with Hubie and Bertie, an early version of Claude Cat and a prototype of Hector the Bulldog.
[2] At Uncle Tom's Cabins, Porky is trying to get some sleep, but mice Hubie and Bertie are down there stealing food and breaking things against his will.
With no other options remaining, Porky resigns to the old saying of "if you can't beat 'em, join 'em", singing along with the dog and the cats.
Trap Happy Porky is available unedited and restored with its original opening and closing titles on Looney Tunes Mouse Chronicles: The Chuck Jones Collection.
