You can help raise the temps by reducing the bedding, but you need to be careful if you do not have thermostat that regulates the heat mat. I'd also recommend that you cover three sides of the tank with some cardboard or another insulation. That will help the general overall temperature. Another option is to get a small heater and just increase the temperature in your room.
It sounds like you have a good plan to get that little one to a vet. It's the best thing you can do. Best of luck, and let us know how it goes.![]()
