I found something interesting.
From The Lost Media Wiki
I found information that the cartoon was actually broadcast in Italy in 1972, the channel was called Raiuno (Rai 1). According to sources, from the online archive of the weekly magazine Radiocorriere TV (at that time the official newspaper of Rai), we learn that the film was broadcast on Wednesday, February 9, 1972, at 17:45 on the Raiuno channel, in the daytime. All information can be found https://alemontosi.blogspot.com/2019/02/la-volpe-con-nove-code-1968-il-film.html?m=1
