Up 'n' Atom
This is one of the best cartoons made at Screen Gems, the main reason being probably that it was written by Bob Clampett.
It stars a favorite of ours, the cat-that-looks-like-Sylvester-but-Sylvester-he-is-not. My favorite part is when the sexy female puppet says to the cat that if he wants something all he has to do is just whistle and the feline character starts to whistle in every possible way.
According to my friend Larry T this short looks like a Davis cartoon made at WB. I strongly agree.
