Nothing I've ever heard of along those lines, though I'm not exactly an expert. I read and watch a lot, though and haven't seen it come up at all.
Eating and lifespan is likely just as random as for any other animal.
Only concern I've heard mentioned anywhere is that in highly paradoxed animals (i.e. 50/50 color/pattern overall), is that there can be concern about which set of genes will pass on genetically when it is bred.
(I.e. a banana pied with normal pied paradox scattered throughout, is it able to pass on banana and pied or only pied?)
