Sometimes you have to leave the house without your pet, may that be just popping to the shop or leaving the house for your job.
If you do that and feel quite bad about it then you might be interested in a Kickstarter campaign that was launched this week, called Sego.
The project was launched by a startup named Sego Robotics to provide a robotic pet companion and sitter for your pets, providing your pets with interaction while you are not at home, with the capability of interacting with both cats and dogs.
It can also feed them while you are away, and you can access the robot remotely should you choose to via a smartphone application.
You can find out more about the robot at the source link below, where you can back the project if you are interested.
