i think you need to get isis fixed. it may be because shes not, shes emitting a hormone that makes him go nuts like that. i'd say shake a can of pennies at him, but that would involve you scaring isis as well...hmm...yeah, like i said, get her fixed. look into places, i know there are ones EVERYWHERE that do it for free. if you move back here and she's still not fixed, i know of a place that helps with that, here.
