A fly on the wall...

Have you ever wanted to be a fly on the wall? I expect this fly has never felt so popular... I walked into the bathroom earlier to find Twinkle and Sparkle sitting side by side on the toilet seat ENGROSSED. They were staring at the ceiling and, (unusually), completely ignored me as I walked in. It took ages to realise that they were watching a cheeky chubby fly on the wall! He was miles up by our ceiling so there was no chance of him being caught, but the kittens thought it was amazing!
