Alright I got the weight of the snake today. I called in and had them weigh it. In November he weighed 100 grams and today he weigh 118 grams. To me that doesnt seem like a lot of weight gain in 3 months but I am new to snakes.

Also can you have two heating pads on the same thermostat or no?
Does a digital thermometer for fish tanks work for measuring temp in the tank?

I told them no more force feeding him. I am printing out what you all have wrote and showing the manager what experienced people have said. Thanks again!
