According to the Humane Society for the United States' website:
The House of Representatives approved an amendment to its Agriculture Appropriations bill that will help stop the practice of American horses being hauled to slaughter plants for human consumption. Details here.
The House also approved an animal protection amendment to the Farm Bill. This amendment would prohibit the use in research of dogs and cats obtained from random source "Class B" dealers, who may steal pets or fraudulently obtain them through "free to good home" ads. It would also ban the use of live animals in sales demonstrations of medical devices. Details here.
Good news on both.
