That reminds me of how Timber acts with everyone but me. He seems to enjoy a "cage game" or sorts. When my husband or my son put their hand on his cage, he will lunge at it then wait until they put their hand in another spot then he will run and lunge at their hand. When we first got him, I thought this was cage possession/aggression. As time went by, I realized he was playing. Many times, he could have bitten them if that was his intent, but it doesn't seem to be. He actually bites the cage, not the hand. When my son comes in the room, Timber immediately goes to the bottom of the cage and waits for Dakota to "play" with him. if either of them actually stick their hand through the door inside the cage, he doesn't lunge or run at it. I'm not sure what Gilbert's "intent" is. I guess time will tell! They sure are interesting, and so individual in their thinking!
