Thanks for checking back in.
We ended up taking him in. They checked him all out and everything was fine. Better safe then sorry. Im assuming because the gum was already chewed, and he only had it for at most 2 minutes he was unharmed. Before going in, i read xylitol lowers blood sugar so i gave him a handful of cheerios to possible counteract the gum. Not sure if it was that, or the gum didnt have xylitol but he is A OK
thanks for all your help and concern.
oh btw, my roommate never bothered checking back in to see if he was ok. She hasn't been back to the apartment since except to park for class. incredibly sad but definitely an eye opener...she is no longer welcome in my home.
