The heat pad on my Leopard Gecko isn't doing its job, it's really only making it warm and the heat is barely penetrating the substrate. I have a heat lamp, but it's in use my my Ribbon Snake. Since Ribbon Snakes are pretty cool tolerant and he hasn't eaten recently, should I just borrow the lamp from the snake until I can buy a new heat pad? Unfortunetaly I don't have enough money to buy a new heat pad, and I can't really borrow, since I already owe my mom $20 (2 week's allowance) to cover half the cost of the Gecko...
