For busy people, low-maintenance pets like fish, birds, or small rodents can be good options. These pets require less hands-on time compared to dogs or cats and can still provide companionship. Fish are calming to watch and require regular feeding and tank cleaning. Birds can be interactive and entertaining but also need some daily attention. Small rodents like hamsters or guinea pigs are relatively easy to care for and don't require as much space or time commitment as larger animals. Ultimately, the best pet for a busy person depends on their schedule and level of responsibility they can dedicate to their pet.
