Guy, when I first got Remmy and had to a lot of training (potty training, what not to bother, etc.) Sparky picked up the scolding words very quickly, lol. If Remmy does something she shouldn't, Sparky tells on her with his "no no, uh-uh, bad girl", lol. If he can see her outside, he alerts me if she is digging or something because he has seen me getting on to her, lol. Tattletale and she is busted! Of course, Remmy lets me know every move Sparky makes, too, lol. If he climbs down to the bottom of his cage, that especially gets to Remmy. They must hate each other, lol.
