In all fairness to Mr Darcy, it was in fact Sookie who got muddy paw prints all over my bed sheets!
To explain, first I must tell you that Mr Darcy and Sookie are 'indoor cats' but we built them a cat house in the garden with a tunnel connecting it to a cat flap in our backdoor, so they can go outside for fresh air whenever they choose.
Every morning Sookie jumps on the bed and walks up and down the pillow meowing at my face until I get up. A couple of days ago when she did this I noticed that she was all wet - it had been raining outside. It wasn't until later when I made the bed that I noticed a crime had been committed!
Sometimes it's a good job they're so cute! :)
