Looks like an early version of Top Cat (1961) when the ginger cat leader answers the alley phone. That HB prime time cartoon would debut four years later.
Last appearance of Tyke.
Second of only two "Spike and Tyke" cartoons, spun off from MGM's "Tom and Jerry " cartoons. The first was Give and Tyke (1957). The characters first appeared in Dog Trouble (1942). MGM shut down their cartoon studio the year these two films were released (1957). William Hanna and Joseph Barbera would move on to television with their own production company formed that same year.
The cat in the house uses window blinds to send a message to the cats outside much like an Aldis lamp (aka a Morse lamp or signal lamp). The many navy veterans in the audience at the time would have recognized this. It continues to be used in the 21st century on naval ships and elsewhere around the world.
The alley cats speak in the same voice Daws Butler would immortalize one year later for Yogi Bear. Spike, of course, speaks in the Jimmy Durante voice that he also would recycle for Doggie Daddy.
