Gross story alert!!!!! help with tapeworms.....?

my husband found diarrhea in my kitchen that had a big old tapeworm in it (now in a ziplock baggy)-i have two cats - is there anything I can do besides take both of them to the vet which costs money i don't have?
Update: I am sure it is a tapeworm....it came in two halves, measuring around 12 inches total.
