I have a huge cat...Thorn. Got him at the SPCA in Pensacola 3 years ago...I walked in and they had over 100 cats. So I walked back out (was wearing my uniform so no time to play with the kitties) and just said give me the one that has been here the longest. He is 16 lb, and long and lean...about the length of my torso without his head or tail (so his torso is the same as my torso!). He is a huge predator...although when I first got him, he was very sick. He's better now though :)
Then my dad got a trap for me to trap mice at my disgusting dorm room .... but now that I'm out we have been using it (humanely) to catch other beasts...including a HUGE armadillo!
