Any box will do
More or less, anyway. This is currently one of Robbie's most frequented beds - he has several which fall in and out of favour. He has chewed this one a to give it a customised scalloped edge.
I don't want to hurt Robbie's feelings, but this is a bit of an emergency blip. I did go out this morning to Blackford Pond where I should have got some good photos of a little grebe family with the two adults feeding their two young, but I didn't check my camera battery before I left and it gave up more or less immediately - and I just couldn't be bothered going out again.
