An unwanted guest is threatening animals and even killing them according to residents in Waller County.
It's rare, but some residents in Waller County say they have sited a mountain lion.
The most recent attack was last week where a horse was severely injured.
The owner didn't want to talk on camera, but says he believes his horse was attacked a mountain lion.
The Texas Parks and Wildlife Department says they get siting reports every month, but no confirmed cases.
Waller residents like Gary Smith say there's evidence. He's lost a 100 pound rhea bird.
"Something had to have jumped over this 5 foot fence, which big cats can do easily, and then get in here, kill it, and then they took the full carcass. They didn't eat it in here, and got over the fence and took it away," said Smith.
He says he also lost a lot of livestock this past year.
"We always attribute, whenever we find a carcass of a calf, that it is a coyote, a pack of coyotes or something of that nature. More and more we are hearing about cats in the area, these large cats. We are going to have to start paying more attention to that. What we do about it? I don't know," said Smith.
Texas game wardens say they best thing to do is be cautious. If you see a mountain lion, don't run away. In fact try to make yourself look bigger by standing on a boulder or raising your hands. Also try to distract the animal by throwing a rock in the opposite direction.
This is advice Smith says he will take not just for the animals.
"We have 15 grandchildren that come out here so that is a concern to us."
The horse injured is expected to be okay.
