Can Cats Take Human Birth Control Pills?

Can cats take human birth control pills? No. These drugs disturb a cat's metabolism and nutrient absorption, and long-term use can cause arterial hardening, ovarian bleeding, cysts, pyometra, and mammary tumors, even fatal disease. The ovaries and uterus also change, bringing laziness, overeating, and weight gain. The safe alternative is spaying, best done between six months and one year of age when the cat is healthy and mature.
