Are they doing this toward you or another animal? I'm trying to make the face, lol, and it's not working too good, lol! I think what you're talking about I see kittens do, but not sure about any of my adults. I do have a few that will come up, do a "mreh" noise and head bump me, and Sophie is a big licker, whether it be hand, foot, toe, knee.... whatever she can give her little nuzzles to. I also have some that look at you sorta squinty eyed, and make little "mreh mreh" sounds.
