Is important for pets to have someone who will take care of them and keep them company, it is very stressful for them to constantly change their familiar area and when they leave their comfort zone they may become stressed or simply not have a good time. Pets have no notion of time, so at home when you leave they are simply waiting for you to return from your trip or your work day, so every time the key to the main door rings they are pending, no matter if it's been 10 minutes or 10 days... they're going to be waiting for you.
I am a person who loves animals, I really care about their welfare, pets feel just like a person and it is really important to have time for them.
