Hello just a little question as to what this white milk substance may be in her cage on the blanket liner.I see it not all the time,butwhen I do see it my first thought to it was it to be vomit,but wouldn't their vomit be a greenish colour from all the greens they eat.or like a hay colour?Anyways any help would be much appreciated.

Don’t worry, it’s just excess calcium in the urine. Oh, and guinea pigs can’t vomit

Guinea pigs don't vomit (please correct me if I'm wrong I'm not an expert) Those marks are excess calcium that is removed from the guinea pigs system through their urine. It is nothing to worry about unless the urine is gritty.

That’s urine. You just need to watch if it gets gritty.
What greens do you feed her? If she gets a lot of high calcium foods, then it can cause problems.

Hi! It looks like calcium pees. This is the normal way of excreting excess calcium in the diet. An occasional one is no problem but if you see them on a near daily basis, you want to check your diet (water, pellets and veg) for a too high calcium content.

I feed her mostly lettuce (not iceberg) thats basically all she eats.I have tried almost everything with her.She will eat the odd piece of celery but I heard that celery can be bad for them because its stringy.I have tried fresh dill she just smells it and it just sits there,but she basically only likes lettuce.She eats her pellets, and I will give her an apple slice twice a week she has an endless supply of Timothy hay, but I have tried fresh fruits..like strawberries, little tomatoes, etc she will not touch any of it.Just the lettuce and her pellets and her hay and lots of water.What do you feed a picky piggie?

I have two quite picky piggies who only like lettuce, carrots, beets, and sometimes watermelon. I'll also go out into to my yard and find some weeds that look safe to feed to them. You can try some more food with her to see if she likes them. You can find organic, cheap veg at your local farmers market. Also, if you have a lawn, she might like to spend some time on there.
