A pet sitter cares for pets for variable periods of time while the owner is unavailable. This ranges from a few hours per day to month-long vacations and longer. There are many kinds of pets that need care, from fish, dogs, cats, and rabbits, to reptiles, rodents, and birds. Some pet sitters are asked to visit the owner’s home to take care of the pet various times per day or overnight. Your clients may want to board their pets at your house. The tasks required depend on the pet, but dog walking, companionship, feeding, and playing are the most common.
