Once Minna discovered how cozy it is lying in front of the new heater, it is her favorite spot at night. When purchasing space heater, it has to be very quiet and safe for Minna, so I am willing to spend a little more for a micathermic flat panel radiator.
It takes half an hour to heat up the room without a fan but it's completely silent. I have considered oil-filled radiator but worried Minna's paws might get burned by accident. There is a metal screen in front of the micathermic radiator so I feel safe for Minna to curl up in front of it.
