Yeah... they have done it so many times... and every time I was too late. I kept my camera close. And I was lucky that this grooming ritual seemed to last like 10 min or something. Got a lot of nice shots. Wish I had a better lens though... Now I'm just managing with my basic lens and a nifty fifty... but those are not the best lenses for animal photography. Yeah and I know about the small spat part. Once Pip was so pissed he started hissing at his brother. In his defense he only did this once. What usually happens is that they play fight and then start licking each other in the middle of the fight. Little funny buggers.
