Why does pet reptiles stink up your house?

If pet reptiles are stinking up a house...then the keeper of the reptiles is neglecting them, and is NOT a good reptile keeper. Reptiles should not have any real noticeable odor. Sometimes cage carpets will hold odor...if that is an issue, wash them with bleach, or use paper towel or newspaper instead.

Cleaning cages on an appropriate schedule prevents odor. Even an entire room full of hundreds of snakes should have very little odor--just a hint from the few enclosures that contain urates or feces from that day.

When a snake produces waste--clean the cage. Clean the cages of lizards at least once per week, and more often for species that produce more waste. It's very simple. Reptiles don't smell--their droppings and urine may. Keep their cages properly cleaned, and voila--no smell.
