When I opened the door, after the doe had gone, the cat rushed in and treated me to a good two minutes of meowing as she told me all about it. The other cat had been in my room the whole time, and when the deer first made noise, briefly perked up her ears, but then went back to napping once she realized what it was. She is quite jaded about deer. Why one cat considers deer to be worthy of a lengthy conversation, and the other doesn't consider them worth interrupting a pleasant snooze for, I don't know.
Today is a holiday, so the appearance of a deer on the lawn will probably turn out to have been the most interesting thing to have happened all day. Since it's all downhill from here, I guess I'll go to sleep and miss all the boredom. Heh. I have something in common with each of the cats.
