Hi Barb,
You're absolutely right that FeLV is not an airborne transmissible disease, but it can be spread through bodily fluid, and in a wet environment can survive for about 48 hours outside of the host. With proper cage cleaning, the risk is low, but not quite as low as something like FIV.
This thread on the forums here has some more information on FIV/FeLV if you're looking for more resources or education items for your Adoption Center folks.
