I have 2 almost 5 year old female Guinea pigs, one is a short haired Guinea pig and the other is a long haired. While cleaning their cage a checking them, I noticed that both of them have crusty noses and crust eyes. After cleaning the crust off them I saw that the long haired one wasn't walking much, Both of them are eating very well. I would love to take them to the vet but I dont have enough money to take them there, and there are also non near that can help them. Is there anything that I can do to help them?
