I doubt that it was an armadillo, I have never know one to have red eyes, and make weird sounds. As for the ringtail cat, possibly, but they are rarely sen in east Texas. Ringtails are fairly common in West Texas, but I have never heard one of them make a "weirs" noise, roll up into a ball and bounce away. They usually seek out a tree in the area and try to hide there. Red eyes kinda indicated a rabbit to me.
