After relocating from KDZQ-AM in Denver in the 1920s Hal George Nichols opened the Echophone Radio Shop and worked as a musician. He founded KFOX in 1924 by buying KFON-AM with partner 20th Century Fox, who later backed out leaving Hal with the station. By about 1940 Hal Nichols was already playing what he called oldies and his cat was co-hosting. I have found print references that confirm the cat was "on air" as early as 1946, and still there in 1952 when Nichols died. It was written that the cat could purr on command. The image above is from a post card, they also made pins. In the 1956 book Mr. Tipps author Vivien Robinette mentioned her experience with the program:
" [Nichols] who owned Radio Station KFOX in Long Beach, California, and his pet cat, Barty, a very beautiful and very famous cat who is known all over the world, played a record for me on their daily Memory Room program and dedicated it to me."The book Mr. Tipps is of course about a cat, which starts to give you an idea about the kind of people who listened to Hal's program. In the 1960s Sonderling Broadcasting bought the station from Nichols' estate and flipped the station to a country format sans cats.
