Our kittens are nearly 5 months old now and have been kept in the kitchen during the day up till now (where I am fairly sure they do little else but sleep) but as they get bigger I worry that they need more space and would like to let them have more of the house to play in while we're at work. Problem is, I have no porch so my front door opens directly onto the outside world - where my babies are not allowed to go yet. Thunder is obsessed with the front door and they both race for it when my OH turns his key in the evenings so I know they will be attempting escape as soon as I crack it open. How do people deal with this usually? I thought about making a screen out of cardboard but don't really think it would work. I am also considering coming in through the rear of the house and just shutting them out of the living room but our back gate is a bit tall for me to open from the wrong side Any clever ideas??
