Tom & Jerry (Gene Deitch era) S01E12 - Buddies Thicker Than Water

On a snowy night in New York City, Jerry is comfortably asleep inside a penthouse. Tom, meanwhile, is freezing in the alley below after being evicted by his owner. He writes a note asking for help, slips it into a bottle, and throws it up to the penthouse window. Jerry, awakened by the noise, goes out to the balcony and finds the note. Alarmed, he rushes outside, going down to the first floor of the elevator, and rescues a frozen Tom. He then brings him inside to the higher floor, and after thawing him out with an electric warmer, Jerry serves him a hot meal from dehydrated food.
