Borrow pressure-mounted baby gate (Beaverbrook)

We would like to borrow a pressure-mounted baby gate (the kind you're meant to put across a doorframe) for a few weeks if you have one you're not actively using. We are having a dog stay with us, and would like to block off a part of the house to give our cats a dog-free zone.
If you want it gone forever, that works too : ). Picture above just to give an idea.
