There is only one way to know for certain Todd. Put on your ghillie suit and lay waiting in the grass. When the mysterious cat comes near then spring up and put the patented Overton Submission Choke Hold on the feline and choke it into submission. Weigh it, measure it, take photos of it, collect some DNA samples and turn it loose.
It looks to me like a Texas sized house cat - isn't everything bigger in Texas?
