Cat in a box

I ordered a garden riddle which arrived yesterday and ever since the delivery box has been contested territory. This is Odo surveying us whilst we did the washing up.

I'm thinking of trying a wee wildflower patch under the Rowan tree.  Dad did a great job of removing some smaller trees there and I'm currently in the process of weeding it.  There's a lot of gravel and some nice purple slate in there though. so I'm hoping the Riddle will help to sift it out.  I'ce been gathering seed heads from nice wildflowers whilst out on walks - is that allowed?
