Your question is a little confusing.
If you meant to ask if a carto can be used instead of an atty on a bottom feeder, the simple answer is yes.
If it will feed depends on the bottom feeder and carto combination used.
If you go with a bottom feeder, I'd suggest getting an atomizer for it even if you like cartos. You may find you prefer atty's with a bottom feeder as they produce better flavor.
