This is a silly question because the genes of a cat produce an awareness level which is not up to the task of understanding such things. Genes effect memes.
Memes depend on environments created by genes.
As that environment changes, the memes that live in that environment must change or be replaced by more adaptive memes. I participated in a thread like this about a year ago on Virus. It should be in the archives. The reverse idea, that memes effect genes, is called the Baldwin Effect. This idea is a little more radical.
