I adopted my guinea pig, Sally, from Petsmart last June. She's still young, not yet a year old. She has always been very vocal, entergetic, etc.
The past couple days, she hasn't been acting like herself. She hasn't been eating and drinking much. She drinks A LOT if I hold the bottle for her, but other then that she doesn't touch it. Eating is a different story. I try hand feeding her. Sometimes it works, sometimes it doesn't. If it does work, she only eats a little bit. I even tried giving her treats, like lettuce. She use to love lettuce, she use to devour it, but now she won't touch it. She still chews on her chew toys, so I don't think it's a tooth problem.
Now, she is very lazy. She rarely comes out of her house in her cage and if I took her out and put her in the play yard, she just sits a corner and doesn't move. Before, she'd run laps around her cage and the play yard. Now, it's the opposite. She isn't very vocal anymore either unless I pick her up.
Last night, I noticed crust around her eyes. It wasn't a lot, so I wiped it off of her. So far, it hasn't came back, but I'm still checking out for it. I also noticed her sitting very weird too, in and out of the cage. She'll sit like it seems hunched, and all her hair would stick up. It seems like she isn't relaxed, but there would be nothing bothering her. I took a couple pictures of it to show you:
This one you can really notice it:
Does anyone have any ideas of what this could be? Tomorrow after school, I am going to go around different veterian offices to see if they handle guinea pigs aswell. Thank you everyone for reading this and helping!
