How can i get a cat out of a crawl space?

if the cat comes out try trapping it in a box with the food then try getting a net long enough to scoop the kittens out ? sorry this is all i got my family use to have a cat with kittens in our crawl space if you do get them out try raising them the mom and the kittens try using a flash light to see how far their away try getting a few of your friends to help with this one get a long net have 1 person holding a box with air holes in it then once you get the cat in the net quickly put in in the box and close it try taping it but make sure it can breath then use the nets to get the kittens put them in an other box the drive or walk home open the box let the kittens and mom out make sure its a nice and open room and run like heck to get out of their and shut the door because shell likely be very mad we had to take in a mom and her kittens several times ( my family ) good luck oh and use long sleeved possibly a sweater and thick gloves long pants and boots so she wont scratch you try using sun glasses to protect your eyes ( i may have got to far on the protective clothing )
