I kind of believe that the training option with Dustfeather should come first before the mate option when you interact with him as a she-cat. I only found about this, and I was looking at another device and typed in "y" to his mate option, thinking that I was battle training and I didn't realize what I did until I recognized his mate talk. You don't have to change this Mossy, but I just found it a little annoying, even though it didn't affect my playthrough.
