Sometimes you have to just do it for them if you want it to get done. Setting a good example can also motivate someone to change their ways. My friend got a BP when I did because he "thought they were cool" and I knew where it was headed. Cold snake in a cheap 10 gallon fish tank with no heat or hides or anything. I ended up just buying a heat lamp and thermostat and a couple hides and putting them in there for him and showing him how much more comfortable his snake was now (and it stopped trying to strike anything that moved near it). I consider my money a charitable donation for that snakes welfare.
