I'm having a bit of a panic attack today... I got up this morning and my almost-4-year-old guinea pig, Linney, is obviously ill. She is laying stretched out in the corner and is very subdued- did not eat her hay at all and looks like she is either having trouble moving around or is in pain (she keeps rolling to her side... though when I put her on the ground she did walk back to her corner.) I'll be calling the vet when they open in 20 minutes and taking her in ASAP, but I am so upset right now... and this has quite literally developed overnight. She was FINE last night, she was begging for food, visited with the kids and I and sat on our laps, ran around and ate salad during free time, etc. I have no clue what could have happened overnight to cause this. 8...
