My beardy does that randomly..
just sticks her head up, sticks her beard out like that, pulls it in, puffs it back out and then opens her mouth like she is yawning then licks around her mouth lmao..
thats, not something.. to be worried about right?
lol she does it randomly but theres nothing around to scare her, my two cats but my beardy is high the cats probably cant even see her..
