Funny thing I was catching up on posts and went to see Matts kitty cat and was going to add this to his thread
Good job looking out for your peeps! If the grass was growing up in front of it then it's probably not active most any critter will beat down a path to their door if they're using it much That looks more like an old armadillo burrow they dig a LOT of holes that other animals end up using and now is a good time to take them all fattened up for the winter they aren't indigenous to North America so no closed season and not protected here in Oklahoma and they taste really good

They are insectivores so meat is clean just don't gut shoot them it makes a mess cause they eat a lot of ants but you can still eat them just tell your guests it's pepper LOL, They are a lot like pork and make great BBQ. Easy to trap just set a couple boards leading to the trap they will be guided right in. If something other than an armadillo lives there they will just hop over the boards so you'll know.
Then thought I'd rather post it here and found that I wasn't he first to mention armadillos LOL
Little known facts about Armadillos:
They always have 4 young and all 4 are either all male or all female (true)
They actually don't taste like chicken (or turtle) They are a lot like pork (very true) this one I know for sure
Contrary to popular myth they don't carry leprosy (true) the disease affects them the same as humans and they are used as research animals for it.
In Oklahoma the scientific name for them is Asidedaroadeous Deadeous (could be true)?
And finally, Armadillos are born on the road dead and live life in reverse, Which explains why in less than a week after one has torn the muffler loose from your car it mysteriously disappears. (probably not true)
