The ideal Renaissance man. An aspect of court life was the idea that the ideal Renaissance man should be widely accomplished. This is reflected in Measure for Measure when, the Duke describes himself as âa scholar, a statesman and a soldier'. The courtier's, soldier's, scholars' eye, tongue, sword!
Estrus is defined as the period where a female (in this case, a cow or heifer) is receptive to a male (or, the bull). Estrous, on the other hand, is the whole reproductive heat cycle that a female goes through, from heat period to no heat period (Proestrus, Estrus, Metestrus, and Diestrus).
Cats: Cats normally have their first estrous cycle between 4 and 6 months of age, with the average age around 5 months. The female cat has 2-4 estrous periods every year, each lasting 15-22 days. If she is bred, estrus seldom lasts more than 4 days.
