That is awesome! Gunther usually shocks me everyday with something. I think I was most blown away when I realized he had learned all the other animals names and which one was which. One day I was walking by one of the cats and I said "Hi Cleo". She jumped up in a window and he went over to her and sniffed her. So I said "Find Fuzzy". He walked off and went to the window Fuzzy was in and sat down and barked. Fuzzy was less excited than I was. So I called Gunther to me and had him sit. I then asked him where Cyclone was and off he went to Cyclone's crate. It doesn't sound that amazing now but at the time I was tickled pink. Now if I'm looking for Cleo I just ask Gunther to find her. He first goes to all her favorite hiding spots and he won't stop until he finds her. I don't think the cats like this game, but it can be very useful to me.
