VictorMultiple Catch - The Humane Live Mouse Trap - Live Pest Control Trap for Mice #M333

I have a pet mouse. (I know. odd pet choice) I wanna get this just in case they escape their cage. is this, for sure, no kill?

Does it come with instructions?

Just received. looking at it...can't figure out how a mouse is going to find a way in...? the little metal flap is covering the entrance. what am i no

Is the hole big enough to trap a chipmunk?
