If men are compared to animals they are wolves, bears or stallions. Lots of women are kept in suburban homes like battery hens or pigs - continually pregnant, bored, depressed. As well as being a massive torture industry, vivisection is another way of objectifying animals. Lots of experiments, such as the Draize test destroy the animals' eyes, turning them into objects who can't return the male gaze. Women and animals are experimented on without their consent by male doctors.
Caesarean section is the standard way lab animals give birth, as it used to be for women.
Lots of pornography portrays women as animals. The whips and chains of bondage imagery is based on gear for breaking in horses. Lots of men who abuse women start off abusing pet animals. Abortion in early pregnancy isn't murder in the same case killing animals is - medical evidence suggests foetuses can't feel pain before the seventh month of gestation. It's true that most of the Animal Rights movement is a whiter shade of pale.
