What pronoun is used for pets?

In some cases you can use the same pronouns for animals as you use for people. For example, the plural pronouns they, them, their, and theirs can be used for people, animals, or inanimate things.

Examples:

Jack and Jill are here. They brought a pail of water.

Our dog had four puppies. We don't have names for them yet.

The new houses look the same except their doors are different colors.

When using pronouns to take the place of nouns for animals, the gender specific pronouns can be used when the gender of the animal is known.

Examples:

The mother cat is very protective of herkittens.

The star at the zoo is a polar bear. He is very popular.
