is my guinea pig ok?

[MookaGuineaPig]

Hello everyone,
I'm not sure if my guinea pig is ok. This morning I cut some grass from my back yard (I made sure that it hadn't been mowed or anything) and gave my pigs some of it. They finished it quickly so I gave them a bit more. I didn't give them very much. Since them, one of my pigs has been acting a little weird. She's been lying down most of the day, and every so often she'll make a whining noise. Her poops are mostly normal, although I did find one that was a little weird. She got excited when I gave her a slice of bell pepper, and she is drinking and eating her hay, but I haven't seen her eat much of her pellets. Do you think she is alright? Should I be worried?

She's likely ok, unless the grass had an pesticides/herbicides sprayed on it.

But when you give fresh grass, you need to start out with a small amount and work up to larger amounts over several days. Too much fresh grass at one time can give them bloat, and that's an emergency.

Okay, thank you so much! I've been giving them grass for a while now, but I may have given them too much this week. I'll try to cut down on how much I give them. They just love it so much!
She hasn't been making the noise for a while since I posted this, so hopefully that's a good sign!
