Pet sitting is generally of two types: Pet sitters that come to the house at specified times to feed, allow bodily elimination, and exercise the pet are the most common. Other pet sitters will not only care for the pets but can stay at the pet owner’s house so pets have constant companions, or at least night companions. Pets can also show signs of stress when their owners are away but it tends to be less severe when they are in the familiar surroundings of their own homes. In 30 years I have yet to treat stress induced bloody colitis in a pet that has been cared for by a sitter. Having sitters also has the advantage of protecting the pet owner’s home. Newspaper and mail collection by the pet sitters eliminate "away from home" signals to possible “bad guys.” Pet sitters create near normal household activity that also discourages potential robberies like bringing in newspapers and the mail, they can care for indoor and outdoor plants and alternating indoor lights. Pet sitters are more likely to recognize potential health problems sooner and can arrange for the pets to be seen by a veterinarian. My experience is that pets with pet sitters tend to be less subject to separation stress.
So, Which is Better - Boarding or a Pet Sitter?
To me the obvious choice is pet sitting. It is as close to a normal environment for the pets as possible and is also great insurance against crime. It is my personal choice for my pets."
