Students at Holland Park State School donned pink shirts this morning to remind the community that "pigs are mums too" in the lead up to Mother's Day.About 50 parents and teachers gathered to hear the Year Six students speak about the horrors faced by sows who are kept in small cages.They told of pigs spending their short lives in stalls no bigger than two metres long, with little room to move and care for their young.The Pink for Pigs day was organised as part of the school's active citizenship curriculum and students have been working for several months to educate the community.The school has also hosted fundraising days and previously distributed information leaflets to families.Today the students gave presentations and performed a song to raise awareness of the issue.Dozens of posters decorated the stage, emblazoned with statements like "save our bacon" and "pigs love mud, not cages".RSPCA education officer Claire Boyce said educating children was the key to changing the way pigs are kept."People don't like to think where their food has come from, but the RSPCA likes to encourage people to be aware of how animals are treated," Ms Boyce said.While free-range pork was not yet widely available, she encouraged people to ask their local butchers for advice."With more promotion and awareness, I think it's only a matter of time before we see sow stalling banned in Australia."
