I found this information on PETA website about a Pearland girl by the name Alena Hidalgo. Quite an interesting case:
Alena Hidalgo of Pearland, Texas, spent months getting to know Gizmo, the pig she purchased through the FFA. It didn't take long for the two to bond as Alena played with Gizmo and cared for him every day. She saw him as the unique, sentient, intelligent being he was-not as food or a "product" to make money from. So when the time came to send Gizmo to slaughter, Alena knew that she had to do everything in her She raised her voice and fought for weeks. Along with her friend Kayree, Alena not only persuaded her school to let her send Gizmo to a local sanctuary but also fought for the life of another pig named Kurtis (who, unfortunately, was sent to slaughter by another student). At the sanctuary, Gizmo is able to spend his days living freely, with no risk of being slaughtered. As for Alena, she decided to go vegan and quit the FFA.power to save him.
