Thousands of mares are abused and milked by constant catheters for their urine for the manufacture of Premarin.
Since they are repeatedly impregnated to keep production going, hundreds of thousands of their innocent foals are considered the by-product and are therefore killed or cast off by the industry and sent to auction where they enter the slaughter pipeline.
The best way you can help is by saying no to Premarin and asking your doctor for one of the many alternatives for menopausal symptoms.
