Hi all! I'm looking for a pet gate to put in my hallway for my 3 month old kitten. I want to create a safe space for her to stay during the day while I'm at work (as opposed to shutting her up in one room). Can anyone recommend one that she can't slip through? I would prefer one that is expandable up to 48" for my largest hallway, but if that is not an option, I can work with a smaller one! Really, I just need suggestions for something that she can't climb under/over/through the bars. Thanks so much in advance!
