I had my sons cat visit here for 1 month,
he is an indoor cat and never tries to escape.
By the end of the month he was darting out into the garage.
The only thing we can figure is because we have an attached garage.
Cats think it is a room of the house that they are missing out on.
The garage door is in the same room as my computer,
I witnessed him scratch at that door to get out whenever the kids went outside....he was extremely social and wanted to always be where they were.
