Hi, Sarah, I have a 10 month old IRN. He is very lucky that my husband & I are well endowed with a sense of humor and that our little Luna is so CUTE. I have learned that the flashing with his eyes ( pupils getting larger & smaller) means differant things. When I am holding him and cuddling him, his pupils change and he is effectionate. ... But, when he is being aggressive and bratty, his pupils gets larger and smaller and he puffs up at me and lunges.

We just have to laugh becouse he is trying to be so bad.

It is naughty behavior. But this is usually over touching his toys or putting my hand up on HIS spaces. He has bratty little temper tantrums just like a little kid in his terrable twos. I just ignore him when he screams or acts bratty. I just walk away and leave the room. His vocalizations turns from screaming or growling to calling me. And even sounds like he is crying sometimes. I don't return or pay attention until I hear him pleading for me to come back. And he gets attention after his behavior changes. On the biteing, I put a towel over my hand and pick him up anyway. To let him know he has a beek, I have a beek blocker and it won't do him any good to be a little blue brat.

Right now I am working on some behavior issues with our Little guy, becouse I think he is kind of spoiled.
