I cannot believe some of the answers on here, what is wrong with people. This lady is asking for help and advice not criticism and abuse. These postings should be deleted. The admin soon delete other postings.
Catsnip have traps you can use. If not please contact Cyprus Pride House http://www.cypruspridehouse.com. If she is heavily pregnant though the vets won't operate on her, its too dangerous. Good for you to help these cats, if you don't get them steralised you will land up with loads coming to your door.
best wishes
