seed theif

yesterday we discovered we had a seed theif, all the larger seeds we had planted sunflowers, sweetpeas, peas and beans. are all gone all thats left is the little spouts just left on top of the compost, we think it may have been a mouse just helping its self to our seeds. it hasnt touched the smaller seeds like spring onions ,tomatoes carrots or any flowers, we have managed to transplant some seeds in to other trays, and actually put some raddish and other veg in to the plot, dont think they will last after we had finished the weather report was that we are going to have an arctic blast this weekend. well the weatherman dosent always get it right, hiope he is wrong this time too.
