Oh no, poor Jitters! She could be suffering from intestinal worms, a severe GI illness, may have eaten something rotten, or could have a foreign body causing her symptoms. Make sure she is up to date on her deworming treatments, giving her one if she isn't. I recommend Panacur, which you can get from your vet. Otherwise, I can give you a home remedy to try to see if that helps. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) in small amounts several times a day for a couple of days. Then slowly add back in her normal diet. If the diarrhea continues on the bland diet, she starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, she will need to see a vet right away.
