Mikodez has been brought up properly - alright, there's some debate over that, from multiple sources, but he doesn't go around just grabbing animals. Even if he really wants to because he likes cats and a talking one might be easier to get hold of than more 'normal' ones who don't always love his inability to keep still.

But he knows how to be polite.

And he happily takes an excuse to try to climb up the tree. To say hello. It's only polite and definitely not reckless or dangerous.
