could be nausea.  when our dogs do that it means that they have an
upset stomach.  Mind you, Foxie dog also does it when he's about to
sneeze (he gets mild hayfever in spring and autumn / fall)

Mine lick their lips when theyare sick at their stomachs, about to
throw up. Dental trouble woud also be something to consider. Hope it's
nothing serious.

In SUgar, that is a sign of nausea. Is she eating ok? Or her gums or teeth
might be bothering her. How does her breath smell?

Tripper does this either when he's got a hairball that he's about to
present to me somewhere where I'll step on it if I'm not too awake,
or if he's been outside in the cat tunnel snacking on grass.  He's also
given to tasting the young rose bush leaves as they try to come up
by the deck.

He has managed to get grass blades stuck up his nose or in the back of
his throat, and this will make him lick as well, though it's also
accompanied by a *lot* of sneezing.

Just keep a close eye on her.  If she goes off her feed or gets
lethargic, don't wait to take her to TED, because even hairballs can
cause problems if they don't get eliminated from the system.

Does she get hairball "medicine"?

Purrs that she's ok -

Otis gets this periodically.  Once, he had some mouse hair caught in his
teeth and back down his throat (ugh) and I had to help him with that.

I've posted about him having this a couple of times since.  He's had lots of
vomiting with these lip smacking sessions and its taken quite some time for
him to get over - like a couple of months.  It didn't seem to be anything
serious.

Just keep an eye on her and see how anxious she seems to be about it.  I've
had cats act like that when they've got stickers up their noses.  But don't
know if Lindy even goes out.

Also when kittens get runny eyes their tear ducts drain into their noses.
So it could be allergy or eye or sinus problem.

The few times we've gone to the vet over something like this it was
something.
