My friend bought a house in sanger she is having a rat problem are there any barn cat programs in Fresno/sanger

Unfortunately no.

Call The Cat House on the Kings cat rescue. They may have connections with people seeking to rehome feral cats, or they may be able to direct you to someone who does. Try to talk to someone in charge rather than just the receptionist. The director's name is Lynnea.

Not that I'm aware of
