Kittens
It had never been noted before that Kirara was a tease; she was faithful, loving and very brave as she threw herself into dangerous situations. She was cute as a kitten and adored being petted, but in reality she was a many times grandmother and far older than her charges. As such she took great pride in keeping tabs on her current litter of kittens.
Truthfully none of them were cats but that didn't matter at all to her, she had adopted them all, even if Sango was her first. Inuyasha may have thought that the rag-tag group were his pack, but that was just because he was a pup and had no real idea of what a pack should be. He didn't even know how a good kitten...pup, should have respect for his elders; but he would learn.
Kirara sighed; she hoped that they would have time to grow and learn, this litter was in terrible danger for ones so young, but despite the fact they fought with one another as all kittens do, they also loved and protected each other. That made her frown as she remembered the others; they too were part of this litter, but not all the time and the older one was just so arrogant.
Oh, she was not bothered by the stupid spats the two pups engaged in; the older had not yet killed the younger even if he considered him a runt and therefore the chances were that he wouldn't, but all the dissension wasn't helpful in the fight against Naraku. Kirara wasn't going to put up with his demeanour either, she was older and wiser than the Taiyoukai pup who, even if he was a Lord, wasn't beyond correction.
So every time the two groups met, Kirara would have her say; it may have only been 'sweet little kitty sounds' as Kagome called them, but the older pup could understand her and that was all that mattered.
Kirara told him to mind his manners, to act more adult in his dealings with her young litter; after all, he was the eldest kitten...pup, she had and he should be more responsible. It was unworthy of him to pick fights with his sibling. If he remonstrated, she would answer that yes, of course she knew who he was, she'd known his father and his mother very well.
She had no fear that he would harm her either, he was not actually a vindictive character in the main and Kirara knew how to cajole and soothe after she had given him a scolding. But the worst insult he gave her once was to ignore her wisdom and pretend he did not hear her; then it had been fun to come behind him, change to her full form and growl down his ear and listen to his bark of surprise. The fact that such a sound had been forced from him made his cheeks pink ever so slightly and he never ignored Kirara again.
