Weight Loss Eating but losing weight

That is a loss of less than one ounce. I would weigh her daily. If she continues to lose weight, take her to a vet ASAP. Are you weighing her at the same time each day? If not, start doing so.

I'd recommend getting an x ray.

Ok, well after talking to my mom(shes a nurse), she said that since I have seen this weight drop every since I added my 3rd guinea pig to the mix, I should seperate her for a week or two and see if she gains weight, if she does then I know she needs to be fed seperate from now on; mom says its process of elimation. Of course, she also said, being a cancer nurse, that if she doesn't gain weight and keeps losing it, it could be stomach cancer, ekk!!!

But Im a little uncertain about seperating her, could I just seperate her for an hour morning and night for her to eat her veggies, mushy pellets, and hay by herself. Or I was thinking of seperating her, but letting her spend 2-4 hours with her buddies a day, but that would be really hard on their social life wouldn't it?? Shes at the bottom by the way, but even though she is, theres always a way for her to get food. What do you guys think, Im going to start with just the hour morning ad night today, till I get any replys.

I would make sure that you have hay (and possibly pellets as well) in several spots in the cage so they can all get to them at the same time. It's fine to take her out for an hour or so to feed her veggies separately, but hay should be most of her diet. I would leave her with her buddies most of the time though since guinea pigs are social animals and are not as happy kept alone.

I would still get a vet appointment and rule out teeth issues or other medical problems. And be sure to weigh her daily.
