Do rats turd and tinkle in their food?

I've raised mice (disgusting little things), but now need to breed rats to feed my finicky BP's. I made gravity feeders for the mice because they tended to turd and tinkle in their food. Will I have the same problem with rats? or can I just leave a bowl in the cage and feed them that way, until I can make a rack set-up?

rats like taking food and hiding it so it may get peed or pood on by proxy, but i don't remember my rats (i had pet rats for a few years) really making an effort to eliminate in their food.

Rats are a Coprophagia species (poop eaters)...

And they tend to defecate/eliminate when they eat, and being that they perch on the edge of their food dish to eat, they also tend to defecate there.

They go where ever they happen to be at the time...that, and they're notorious for knocking the food dish over too.
