Over the years, I've written about how Max and Rocky occasionally play together. They don't physically interact (unless Max is pulling Rocky's tail or buzzing him) but they will be together in the same place, in relative harmony.
They've been doing this more frequently lately; usually initiated by Max. Rocky pretty much minds his own business but will occasionally threaten her if she gets too close. I took a few videos of this over the weekend.
We were listening to a new CD, one that I know Rocky had never heard since it came out after we adopted him. There was something about the song that starts shortly after I started making the video that caught his fancy. If you listen closely, you can hear him singing along (in a high-pitched, out-of-tune voice) for a second or two. Then, he starts clicking and dancing, only pausing for my comment. I stopped taping then, but he continued this for the rest of the song.
