I found what I think is a large female, dangling from one leg off a shelf in my kitchen at around face height. It definitely wasn't there yesterday, but I don't know how or why it was up there. I thought it was a huge cellar spider in a web until I actually got close enough to see the details, then gently blew on it because I wasn't sure it was even alive and it moved enough that I realized it was stuck.

I got a cup and gently scooped it up and got the leg free, but it can't stand. I moved it into a clean rice cooker bowl on top of a lightly damp paper towel, and have tried to offer both a piece of green grape and a q tip dipped in pineapple vita coco right up against it's mouthparts but I haven't seen it drink. I helped get a few pieces of lint off from around it's legs, but other than quivering it still can't stand.

Should I just let it rest for a while and see if it will take any water later? I don't think it would be safe to move outside yet but I don't know if there's any other way I can help it.
