Going on vacation
Of course, we all like to get away for a week or two. The question is, what do we do with our precious pets? There are several common options. One would be to have a reliable friend stop by every other day to feed your animal. Your lights can be set on automatic timers. Remember to be sure your animal remains on its 12 hour photoperiod (light on at 9am, off at 9pm). Another option would be to board them out. Many pet stores offer this service on a day-to-day basis. If you're only going to be gone a few days, feeding your blue tongue a regular portion of food before you leave is fine. DO NOT leave water. Blue tongues are very hardy animals, and will be fine for just a few days. If you leave water, the chances of them defecating in it are high. Then when they drink it...bad news. Do not get a few days mixed up with a few weeks! They cannot go without water for weeks at a time. Remember to be sure you have automatic timers for your lights, and that they are working properly...proper light and day is more important than most people think. Be VERY cautious with timers however, whether you're on vacation or not. While handling your blue tongue, you will obviously remove the heat lamp from the top of the tank (if it is permanently hung, you have nothing to worry about), and place it temporarily on the floor, bed, chair or wherever. Be sure to place it back to its proper place! If the timer kicks in, and that lamp is on the carpet or somewhere else, you will have a real problem. Many people just slide the lid to the left or right to access the animal, and that is fine. Use caution doing this as well, and be sure to replace the lid immediately. If your heat lamp is turned on and gets positioned funny, it could very well melt the plastic edges of your tank creating an ugly and smelly mess."
