+My name is Mark.

+I have 2 cats:
+- Fred is a big, fat, orange, stripy cat.  He is 12 years old and has 4 legs.
+- Hope is a small, black cat.  She is 7 years old and also has 4 legs.
+
+Fred has 4 legs.
+
+Hope has 4 legs.
+
+Fred and Hope are nice animals, but occasionally they fight.
+
+Fred is lazy and sleeps a lot.  Hope is energetic, runs around a lot and
+climbs trees.
+
+Both cats have tails and whiskers like all cats do.
+
+Cats have the species name Felis catus.
+
+The cat (Felis catus), also referred to as domestic cat or house cat, is a
+small domesticated carnivorous mammal. It is the only domesticated species of
+the family Felidae. Advances in archaeology and genetics have shown that the
+domestication of the cat occurred in the Near East around 7500 BC. It is
+commonly kept as a pet and farm cat, but also ranges freely as a feral cat
+avoiding human contact. Valued by humans for companionship and its ability to
+kill vermin, the cat's retractable claws are adapted to killing small prey
+like mice and rats. It has a strong, flexible body, quick reflexes, and sharp
+teeth, and its night vision and sense of smell are well developed. It is a
+social species, but a solitary hunter and a crepuscular predator. Cat
+communication includes vocalizations—including meowing, purring, trilling,
+hissing, growling, and grunting–as well as body language. It can hear sounds
+too faint or too high in frequency for human ears, such as those made by small
+mammals. It secretes and perceives pheromones.
