Heat and Electricity went out, what to do?

Hello everyone, around 4 am my roommate noticed that the furnace stopped working. The landlord has been contacted and he sent people over but they’re not supposed to arrive until 2 today. While waiting for them the power went out and flipping the breakers didn’t do anything. I have a cat and my other roommate has two cats. If anyone was any advice/tricks to stay warm it’d be much appreciated.

Edit: the power has come back while waiting for the furnace repairmen. So I have a space heater running rn. Thank you all for the advice, I’ve started researching pet friendly airbnbs/hotels incase the repairmen can’t fix the furnace today
