A pet sitter is a person who takes care of pets while their owners are away. This service can include feeding, walking, and providing companionship to animals such as dogs, cats, and other pets. Pet sitters often visit the pet's home or may offer boarding services in their own home. Many pet sitters are trained in animal care and may have experience with various types of pets. They can help ensure that pets remain healthy and happy during their owner's absence. Some pet sitters also provide additional services like administering medication or maintaining the pet's hygiene.
