My guinea pig has been behaving strangely. She hasn’t been taking her vitamins, she has a powder sprinkled on her food and she always eats it but she isn’t now. She’s been leaving some nuggets as well. She keeps sitting in corners, facing the walls. And her poop pellets have been half the size and thinner. She isn’t drinking as much water. She’s been really skittish and scared of everyone recently. She’s normally very social but now she hides and avoids everyone. I think she may have lost some weight but I don’t own any scales to be sure.
