A lot of truth to this. I remember being a kid... Didn't want to eat dinner because I didn't like what we were having. 8pm rolls around and i was hungry. My dinner plate that mom put aside was there for me before I could eat anything else. Believe it or not, I ate it. lol. Happened a few times.
This is very interesting though.. as I thought they only really cared about prey that had a heat signature and smelled good. it would be neat to see if you could offer a white one, and then there was a safe way to color the fur and re-offer the same prey to see if it made a difference?
