Your home as well as your pets will be looked after while you are away. Mail and papers can be brought in, lights can be turned off and on, curtains or shades opened or closed and trash and recycle can be taken out. This will make your home look like someone is there even when your not.
The extra services such as the mail / trash / plant watering /etc. are all included in the price of taking care of your pet. As long as services can be completed in 30 minutes, they are included. The majority of time is dedicated to your pets however. I want them to feel that I am there just for them.
