Deer!!!

When I went out to feed the cats this morning, they were all missing. I went around the yard looking for them and found out why they were scarce ... deer! There are two deer in the yard, a male and female.

But what's odd is that I don't live in a rural area but a suburb with lots of traffic. How did they get here without being hit by a car or eaten by some neighbor? Here are a couple of photos I got of the male deer by the bird bath ....
