Orally administered contraception for dogs and cats became available in Europe in 1963, followed by the US in the 1970s. [4] [5] The initial products were mostly progestin-based treatments implemented for sterilization. One of the first drugs sold was medroxyprogesterone acetate (MPA).
At higher doses (100 μg/spider), the shape changed more, and the web design became irregular. All the drugs tested reduced web regularity except for small doses (0.1–0.3 μg) of LSD, which increased web regularity. [12] The drugs were administered by dissolving them in sugar water, and a
