Many new intakes, and those who are adoptable, need to be spayed. We always spay and neuter each new resident and/or adoptable pig.
Not only does this make for a more friendly and laid back piggy, but it also assures they will not develop cancers associated with unaltered pigs. Testicular, ovarian, and uterine cancers are highly prevalent with unaltered pigs. This is literallg a life saving procedure for many pigs!
