hi there, welcome to the forum
Oh dear like helen says, that looks painful! i would definitely try ringing the vets & get them to check him over, looks like you might be lucky & the eye isnt actually injured only the skin around it.
Please ask the vet to organise some painkiller (metacam), pain often causes guineas to stop eating or cause a reduction in appetite which then becomes a whole new ball game of problems
if you ring for your usual vet, they should give you out of hrs/emergency vet details. bathing with boiled, cooled water is a good idea, even if you put a tiny pinch of salt in it, this will help clean the wound (not too much, only the tiniest of pinches or it will sting horribly).
they may give you an antibiotic to prevent any infection in the open wound.
Do you keep him in a cage or hutch? maybe a sharp bit of mesh/ hay rack damaged has come away & caught him in the face, does he share with another guinea? have you noticed them fighting at all? might be worth checking.
if you are from the uk there is a handy recommended vets locator that you can use if you dont have him registered under a vet or your vet isnt cavy savvy
Healing vibes to piggy, whats his name?
keep us updated.
speedy recovery from the girls & i. xx
