Thank you!
Yes, that sounds just like my staircase. We have an overlook or cat walk that is the upstairs hallway that would be about 10 feet. My cats have NEVER tried to go down through the slots, are dogs any different? I know while she is a puppy I have to totally supervise her since she really doesn't know better, but what about when she is grown? I know my neighbor's yorkie has free run of the house....I'll have to ask about she does on the stairs and upper hallway.
