Then George sees animals that have to live in a cage. He sees rabbits, guinea pigs, and mice. Mice are what you call more than one mouse. He likes these animals because they are small. Birds live in cages too. George sees a parrot and a canary. He likes them all, but he doesn’t want to clean the cage.

George sees the animals in tanks. The tanks full of water have fish and turtles in them. He thinks about a goldfish but decides he likes the turtles more. There are also tanks with rocks and sand that have snakes, spiders, and scorpions, but George is afraid of them. George likes the turtles best, but they won’t fit in the little fishbowls.
