My guinea pig has an infected eye!

My poor guinea pig has a horrible crusty eye. It is yellow and is like ball sitting ontop of his actual eye! He is in no pain and is eating and drinking the same but it looks horrible. What should i do?
   
Thanks Meg

That's a common eye infection, due to lack of vitamin C. Guinea pigs need a lot of vitamin C.. You should put some type of vitamin C powder in its water, or buy liquid vitamins for guinea pigs at a pet store. It's very uncomfortable for the guinea pig, and you should see a vet for eye ointment. Also feed the guinea pig apples, oranges, bananas & green vegetables for added vitamin C. I used to have four guinea pigs of my own. : )

Hi thank you for the reply but i dont think it is that. I have 7 guinea pigs so i know when they have a lack of vitimin C. Just before i wrote this message i gave them some greens, and they have plenty of muslie packed with vitimin C. Also like i said before he is in no pain and when dab his eye with no water he does not jerk or squeek. I think his has got into some sought of fight and it has got a bit infected.
   
Thanks anyway. Meg.
