Rats make excellent pets! Often compared to dogs due to their high intelligence and social nature, they can be the perfect pets for people who cannot have a dog. Pet rats can even be taught tricks. They are clean and love attention from their humans. Some rats even get along with other pets, especially dogs and guinea pigs. Since they are social creatures, they should be kept in same-sex groups of two or more, but those owned by rats find that they bond just as well with their humans as they do with their cagemates.
