Hello, I bought a female guinea pig, JuJu Bean, from a pet store 3 weeks ago. I have recently noticed that within the last week that she is looking very plump and feels noticeably heavier (she is held on a daily basis). I have also noticed that she is drinking 3 times more water than she was last week and she is pooping a lot more as well. Shealso seems to have gotten very sensitive around the sides and under part of her belly (she wasn't before), she also seems to be having a bit more trouble leaning forward to clean herself. I have also noticed that her belly is firmer than it was last week. I took her back to the pet store to see if they could tell me whether she was or not and they said it is very likely that she is. Can anyone tell me their thoughts on this, please?
