The temp you really need to check is the floor because heat rises. A house thermostat doesn't temp the floor so whatever the temp is for you, it may still be cooler on the ground. My floor is always colder.... Too cold for my torts.
My thoughts exactly. If the room temp in the apt. is 22, I'll bet the floor is significantly cooler.
Check your floor temp Princess Jay, not the air temp 5 feet up on the wall.
