In my previous reply to F. Lamarche's question, please take off from the
last line of Remark 1:

"   (or cardinals as well)   ".

The site of cardinals  1, 2  also has the non-trivial involution  2 -> 2;
its topos of presheaves is
"INVOLUTIVE reflexive graphs" (which is also of interest in homotopy, of
course).
