Couldn't bring anything up on this.
We had a 12 pound black half Siamese cat who kept our Dobermans in order for years. I got a lot of strange looks running a big Dobe around the track with a black cat running behind, screaming at us for leaving him behind. He would slap the Dobe for leaving him, then rub against him and trot beside him all around the track. The looks on other peoples' faces were a study in disbelief.
