I devestated, it looks like Urchin has escaped. I opened some windows to let some fresh air in today, they are ones that pull out so only a small gap is made. They are side by side so if one closes there is a gap down the side. I totally forgot when I went to work and remembered when I got home. They were both still open ( no gap) but I can't find Urchin. I can't see how he has managed to close one window, climb through the gap and re-open the window, but he is gone. I've looked everywhere, in the cupboards, pulled all the bedding off the top of the wardrobes and can't find him.
I feel so guilty, and he must be so scared and there will be fireworks starting this week. I can't believe I've been so stupid.
