Please don't let your kitty eat chocolate- the caffine in it can be toxic. I suggest putting all candy out of your kitty's reach for his own safety. It can cause serious problems if he gets ahold if it.
Oh yeah, I know! I would never ever let him EAT it! I take it out of his mouth when he gets it, and I closed the bag up now, so everythings all safe! Sorry to make you worry!
