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.
The cat in the house uses window blinds to send a message to the cats outside much like an Aldis lamp. The many navy veterans in the audience at the time would have recognized this. It continues to be used into 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 would also recycle for Doggie Daddy.
The score for this cartoon was featured on the audio CD "Tom & Jerry & Tex Avery Too!".
