The term "pocket pets" refers to a group of small animals that are suitable for keeping as indoor pets in small enclosures or cages. These animals typically require minimal space and care, making them ideal for people who live in apartments or have limited living quarters. Examples of pocket pets include hamsters, guinea pigs, gerbils, mice, rats, and even some species of reptiles such as geckos or chameleons. These animals are often kept as companions for their ability to provide social interaction and entertainment for their owners.
