My cat was "playing" (aka torturing) with this centipede:
I tried to measure its length with a measurement tape:
When the cat tried to catch it, the centipede ran fast to below the carpet or my slipper. Now, when I lift the carpet, it pretends to be dead, although in one occasion the arthropod moved its legs without changing position.
If it matters, I'm in Southern Brazil in a subtropical region and it's 01:30 AM. I don't think it bite my cat, since I'm not seeing any signals of health problems on the cat (also the anxiety of being forced out of my room so they can't interact until I solve the situation).
I think this animal is a Scolopendra, known here as "Lacraia".
