I hope you do find someone to give them a good home. Responsible, adult pet owners do not outgrow their pets. They care for them to the end of their days. Sometimes things do happen though and people do have to find new placements for their pets. If you don't want them anymore, at least take the time to find a good place for them. Taking them to a local no-kill shelter is also an option if you can't find anyone to adopt them.
