Help! CAT problem!?

Just be patient, as long as it is safe then you don't hat to freak out. You can try luring it out with some food. Don't scare it or be too loud. I'm not sure what kind of layout you're in but you can try to get it to move out into another area, or move the furniture it's behind just be careful you don't hurt it. You can also leave it alone till it sleeps and then get it. If you have to wait make sure you have food and water for it.
