Is There a Doctor in the Mouse? is a 1964 cartoon and is the 130th one-reel Tom and Jerry film directed and produced by Chuck Jones. The title is a pun on the famous phrase "Is There a Doctor in the House?"


Jerry mixes and drinks a potion as the title card and credits are shown and after he drink it, he discovers that the potion is giving him the ability to run (and eat) at blinding speed; he tests this out by eating Tom's canister of sardines, along with the last bit of gravy and bits of his skin. Afterwards, Tom initially comes under the assumption that a ghost was eating his food, but concludes that it's a bug equipped with a jetpack and chatter-like teeth.

Tom slips a large watermelon slice around the corner and readies a flyswatter. Jerry mows through all of the watermelon flesh and Tom only ends up scattering the rind and seeds around. When Tom sees an entire turkey being eaten, he panics and takes a grape cluster and an apple from the table. Jerry proceeds to eat the apple down to the core, then rest of the fruit and the grapes. After going berserk, Tom hides in the refrigerator and attempts to eat a stack of ribs, which Jerry proceeds to eat.

Tom then sets out a cake and films Jerry stealing it so he can see who is taking his food. After Tom prepares the film, he plays it in slow motion. He mutters (Why that mouse is so strong!) Afterwards, Tom sets up a mousetrap sandwich for Jerry. Jerry does take the bait, but doesn't trigger the trap. After Tom triggers the trap from attempting to bite Jerry, Jerry takes a banana from the refrigerator. When Tom grabs the banana and peels the skin, Jerry taunts him by kissing his nose, then runs off. The effects of the potion wear off, and Jerry barely escapes Tom.

Jerry makes a second potion which makes him grow to an unbelievably large size. Tom catches the mouse's tail and somehow manages to pull him through the wall. When Tom can no longer lug the load around, he turns around to see the mega-Jerry sadistically raising his eyebrows and waving at him. Tom begins to laugh at the super-sized Jerry finding it as a joke, but then begins to cry, implying that he's really in trouble as the cartoon ends.


  • The way Tom catches Jerry in a giant size is a reference to another Chuck Jones short called Soup or Sonic where Wile E. Coyote "catches" the Road Runner in a giant size.
