Taking on any pet requires a commitment to provide proper care for it during its life and in the case of rats this can be for 2-3 years or longer. A rat will need attention and daily care and feeding. In addition a rat may require veterinary treatment if the rat becomes ill which can be costly.

A child cannot be expected to provide all the care and finances required to keep a pet rat, particularly if the rat requires veterinary treatment, so it is important if buying a rat for a child that an adult member of the family is prepared to share the commitment of owning a rat.
