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!
