Yeah I was kind of wondering about that too. Reggie and Smokey definitely do the leg lifts...ALL the time. I think part of that is probably the fact that they spent basically all of their lives unneutered. They are neutered now, but Smokey was maybe 4 years ago, and Reggie just a few weeks ago. I plan on neutering Nebo when he's about 4-5 months old. I don't know how Nebo could miss seeing Reggie/Smokey lift their legs, but I don't know if he will develop it if he is neutered that early. I find it annoying that they lift their legs on EVERYTHING, but I'd rather he lift his leg, or people might mistake him for a girl, lol.
