Narrator: What fills the monster's heart with fear? What does he see in the sky? Why, it's Mighty Mouse! 4:23

you're right,paul terry was downright genius!

I remembered this from when I was a kid almost fifty years ago

The animation on these classic shorts is UTTERLY fantastically amazing

5:08 Huh, this is actually the first time I see a villain who actually puts up a fight with Mighty Mouse.

3:15 Next to Snake Poison you’ll see a bottle that says Beetlejuice. A reference to the movie under the same name!

Love ur cartoons..

Anyone else notice the bottle of Beetle Juice on the shelf when the cat was mixing the poisons?

I’m not going to be able to make it tonight but I will have to pick you guys up after work.

I used to be terrified of that Hyde cat when I was small! 😁

Back when cartoon shorts had some guts - they weren't afraid to kill off characters!

CAT💖

I remember this cartoon SO vividly from childhood - especially after the cat takes the poison. It scared the hell out of me, and it's the first time I've seen it since the mid-50s. Thank you so much for posting this. I didn't know the title, so went through all the Mighty Mouse titles, and finally......"Jekyll & Hyde Cat" - THAT DID IT!!!!

Supermouse vs The Incredible Hulk Cat!

Damn, that stupid cat basically just poisoned himself and had an instant death mixing all of those poisons and chemicals together and then drinking it.

Does anybody know who narrated the Mighty Mouse cartoons?

Off into the thetting thun flyth the champion of mithes and men; Mithy mouthe. They could have hired someone who can pronounce 's' properly.

I mean the background

In fact, Cats are a Pain!

3:48 CAT IN TRO A MONSTER

Não sou criança,mas gosto muito dessas super produção de desenhos animadissimos!👏👍

3:49 eww that tongue

incredible Hulk Catԅ(¯ㅂ¯ԅ)

That tongue on that Hyde cat ! BTW, Mighty Mouse is wearing a Superman like costume in this episode as opposed to the yellow and red one.

I know it doesn't happen here, but why are there so many Mighty Mouse cartoons where he and the other characters sing like in an opera?

Hate those mouses

☺

Blue outfit..........????? Never seen that before.

The narrator says that no one has ever passed through the door into Dr.Jekyll's laboratory,not even his cat. So how did the cat know how to prepare the doctor's formula to transform into Hyde Cat?

Mighty Mouse killed the kitty.

😅😮😅😮😮😮😅😅well ingormeti0n.Good show 😅😅😅

They like the copy of tom and jerry

Nice little cartoon. Although did anyone catch that How did the cat know the formula of creating Mr. Hyde despite never being inside the laboratory. Also mixing poison with more poison, wouldn't that just kill the cat?

I always wondered why they went from this to the opera approach where everyone including Mighty Mouse was singing? I was never a fan of that.
