I’ve just spotted a little mouse in my kitchen scurry up the fireplace. It’s tiny, I have a dog & children that I don’t want to poison, I don’t want to kill it ! Can we live peacefully with my new rodent pet family in the chimney ? All food stored away, bins firmly in bin drawers. Pet food too so nothing open. Mice can’t open drawers ? We live in the countryside. Please tell me it’s not going to bring us the Black Plague and I don’t need to call in the exterminators ..
