ABSTRACT:
The vertical sliding pet door can be used to let pets in and out easily by themselves. The pet needs to be trained in the usage of the pet door, and it also protects the house from unwanted bugs and other creatures such as rodents, as it closes as soon as the pet gets out through pet door. A locking mechanism is also provided, which helps to keep the house secure, when the sliding pet door is not being used.
