		<h3>Dogs Have Better Noses</h3>
		<p>Dogs can discriminate odors at concentrations nearly 100 million
times lower than humans can. The wet nose is essential for determining
the direction of the air current containing the smell. Cold receptors
in the skin are sensitive to the cooling of the skin by evaporation of
the moisture by air currents.</p></section>

		<h3>Cats Have Better Tongues</h3>
		<p>Cats are known for their cleanliness, spending many hours licking
their coats. The cat's tongue has backwards-facing spines about 500
micrometers long, which are called papillae. These are quite rigid, as
they contain keratin. These spines allow cats to groom themselves by
licking their fur, with the rows of papillae acting like a hairbrush.
