My wife was calling to the stray with some food when our fleabag snuck out (hes an indoor cat) and ran over to the stray, after 5 minutes of being nose to nose they decided to have a fight, even when I ran over to them, they didnt stop, I had to physically stop them by grabbing them both.
I went down for a cup of tea about 2 this morning, having carefully listened for any crunching noises first. There was quite a small hedgehog almost standing on his head in the food bowl. I was expecting him to hurtle off at warp factor 5, but he looked up, gave the hedgehog equivalent of a shrug and went back to his dinner. Obviously his Felix was far more enticing than I was scary. He didn't even look up when I went back with my tea.
