@@renarddubois940 I think the main bad guy you mean is Oil can Harry. I've seen some cartoons where other bad guys have put up a fight as well, of course, I don't remember who they were or the cartoon.
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!!!!
Ditto on the effect on me at the same time! Possible reason: the animator for this cartoon, Bill Tytla, also animated Chernobog in "Night on Bald Mountain" in "Fantasia".
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.
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?
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?
