A day at the beach. Tom wants to lay in the sand, but his rest is disturbed by Jerry, who walks by to go fishing. Tom ends up falling off the end of the pier as he chases Jerry and lands underwater, where he encounters a mermaid whose top half looks just like Jerry. A chase, naturally, follows, all underwater. The mermouse, however, runs into a swordfish, and it begins chasing Tom, too, turning into mer-Jerry’s ally, until it gets stuck in what looks like a telephone pole. The chase is next interrupted by an octopus, which grabs hold of Tom until Jerry yanks him free when we discover this is all a fever dream of Tom’s, and Jerry has actually been performing artificial resuscitation.

How to Watch The Cat and the Mermouse Legally and Safely

If you want to stream The Cat and the Mermouse through reputable and legal services, there are a few good options depending on where you are. Subscription platforms like HBO Max, Disney+, Netflix, Amazon Prime Video, and Apple TV+ sometimes carry The Cat and the Mermouse films or related DC titles—though availability depends on your country.

If you’d rather not commit to a subscription, there are ad‑supported, free (but legal) platforms such as Tubi, Pluto TV, Peacock or Crackle (where available in your region) that occasionally host superhero films.

Lastly, don’t forget about library‑linked streaming options like Kanopy or Hoopla (if your library or university is registered), and official uploads by film distributors on YouTube—these can also give you legal access to classic movies.
