Is she due a shed? They do get a bit mroe grumpy at shedding times and will also rub themselves on the vines to get the dead skin off. Is she rubbing her snout or her eyes?
Could she be getting ready to shed? MY Wilson will rub his nose like that prior to shedding. Sorry I have no difinative answer it could be this and it could be something else.... maybe just an "itch" lol.... I am assuming she is acting fine and looks normal in all other aspects yes?
does her skin look pale? if so, like the others said, its time for a shead. if its a continuous thing, i would check for tiny tiny black spots on her skin and check for mites
sounds good buddy. you can always get zoomed's mite off and give that a spray on her body anyways. di that fir a couple days just incase. im sure it isnt harmful to get it in their eyes, it is meant to spray all over the animal head to tail. so im sure it wouldnt be an irritant
