Anole

It's a wild anole. That much is certain, anyone who's had (or regularly been near) a pet anole would be able to tell you that.
That's all I know. Honestly there are so many lizards and geckos and anoles down in Texas that unless you catch one for observation or have studied these things it's hard to tell what they are. They move so fast and you never see their stomachs, it can be nigh-impossible.
The most common anoles are the Brown and Green, but the Green can be brown-ish sometimes as well.
The only really helpful piece of information I gleaned off the internet is that this one is most likely female as many species of anoles have striped females and unstriped males.

Ole anole!

Gecko

A Mediterranean House Gecko to be precise, and a fairly young one to boot.
I went to close my kitchen windows when... boing! this little thing jumped onto the screen. Far from being surprised I grabbed a jar and the baby and ran outside intent on being able to positively identify one of the lizards I've seen. It was by far the easiest wild animal capture I've ever made. I just snuck up and quickly encircled him (or her, I can't tell) and waited until he ran into the jar. I waited and waited and waited. Thank goodness for interior feline assistance that sent this little booger running around, I can not believe how fast he could run. Next I brought him inside to put him in a slightly larger, more photograph friendly, jar. In the second it took to place one jar into the other and cover the larger one, he nearly got out. I may not mind looking at lizards, but I will not stand for one loose in my house. He was intently watched for a little less than an hour and then released to his original place of origin.

As the name suggests, they are not native. They are flourishing though. These Geckos are nocturnal and may be spotted sitting on buildings nearby a light source just waiting for moths and other insects to eats.
Adults can grow to 5 inches long (this one was about 2) and they have flattish heads. The easiest means of identification are these three things:
1) The semi-translucent pale skin. On their heads you can see darker areas behind the eyes that's actually the eye, and if you get a look at the stomach you can see shadows of their organs.
2) The warty back. Each of those little dots is a bump, and they generally get more pronouced as they age.
3) The striped tail. Black rings down it's tail, even though the back is spotty.

And that's a Gecko for you!

Lizard

This little dude showed up after church on Sunday. I think he's a young Texas Spiny Lizard. He was about three inches long with his tail. At first I figured that had to be the extent of the size, that was how big the Florida lizards were that climbed all over the windows, but apparently... everything's bigger in Texas. That means that I can't find any evidence of there being any lizards here that are full grown at three inches.

His scales flip up at the tip, he has the little dark bars across his back, and a very thin tail. I'm not certain, though, as I knew it wasn't full grown and lizards can change a lot as they age.

Texas Spiny Lizards grow to between 7-11 inches long and have scales that turn up like spiked armor.

I don't know what else to say besides that he's a cute little lizard, it's too bad he's going to grow up to be big and ugly.

Texas Rat Snake

Imagine my horror and fear as I went to get my mail and saw a snake nearby the mailbox. I'm talking about 20 feet, but still, a wild snake 20 feet away is WAY too close for me.
I thought it had been run over by a car because it was at the edge of the road and it wasn't moving. My terror that it could be dangerous kept me from getting closer, so I looked and looked and burned it into my memory as best I could.
When I got back I told N I saw a big honking snake that was "this big" 16-20 inches with spots on it's back. He said, "Oh, that sounds like a Diamondback Rattlesnake." I freaked out and spent a good deal of time looking up snake pictures on the internet to find out that it wasn't a rattler at all, I thought it was a King Snake. I put aside the thought until now and looked some more to find lo-and-behold it appeared to be a juvenile Texas Rat Snake.

I thank my lucky stars for three things.
1) They are not venomous!
2) It was not moving!
3) It wasn't full grown!

Full grown rat snakes are generally between 42 and 72 inches and are about a foot long when hatched. They are tan/brown snakes, when young, that have darker spots down their back roughly in the shape of a tanned hide (I've also seen the term "saddle") with smaller spots of the same color going down the sides. These spots generally fade with age and the snakes themselves can appear anywhere on the spectrum from brown to yellow.
They're heads are grayer than the rest of their bodies (usually with a arrow shaped marking on them) and appear slightly wider than their body. That's just something I read, I didn't get close enough to be able to tell.
When it shakes its tail it can sound almost like a rattlesnake, even though they have no rattles. While these are highly aggressive snakes they can't really break the skin when they bite and are constrictors by nature. They are prized for being good at what they do, eating and killing rodents. They are great climbers and will go up trees and into attics in search of prey.
They live primarily in Texas and can be found pretty much anywhere that happens to have bountiful munchies.
