How can there be so many pet stores within my area, including big chain, family owned & those specializing in exotic animals, and yet none of them carry a thermostat? They all carry thermometers, CHE & lamps, but no thermostat. I cannot understand it. Luckily, some of the shops are very friendly and are ordering some thermostats in on their next shipment (arriving sometime next week), so we're not at a total loss. I just find it very intriguing how 2 major chains, a specialist store & an exotic pet store don't carry them. Makes me wonder how they care for their animals & manage the temperature.
