B Albopilosum curled up in the corner

A few hours ago I fed my curly hair and right after it grabbed the cricket it started whating around the cage for a few seconds/minutes and now it's curled up in the corner of the enclosure. (A stress curl) Why is it doing this?

A little more info and a pic couldn't hurt. Did it eat the cricket and then go into the corner, just kill it or let it go altogether? My first thought is a sling and a cricket that's bigger than it is. If that's the case, you'll want to go smaller or feed pre-killed prey. If it's a larger or adult tarantula, it could be nearing a molt and find the food disruptive rather than enticing, in which case you'll want to take the cricket out asap if it's still alive. Obviously you can probably see why more info is needed, because a myriad of things could be causing what might actually not be a big deal.

It's ok now. I think I was overreacting. (lol). The cricket was about the size of its abdomen and it was really curled up and it looked like he was on it's side
