Found on another forum and passed on with permission. Hope it's of use to someone as there are too many unwanted cats in this world already!
"..the Salisbury Branch [Of the Cats Protection League] is offering to neuter cats FREE if
their owner is in receipt of means tested benefits or low income including some pensions. PLEASE CONTACT AIMIE ON 01722 416245 to make an appointment.
If you know of someone who has unneutered cats please pass on this message."
