I have an Aldabra tortoise who is doing great and growing like a weed. I recently purchased several baby eastern box turtles. I tend to do their care one after another as well as feed my group of loggerhead musk turtles. I only have one sink so I cant use separate sinks but each animal has its own water and food dishes as well as soak tubs. I do not prepare their food at the same time nor do I soak them at the same time. I take care of the Easterns, thoroughly wash my hands with antibacterial soap and then proceed to take care of the Aldabra. All dishes are washed using the dishwasher on a heat. I feed the musks last.
