I have a older female cat all of sudden she has stopped eating and has not left my bed for three days except to puke or have diarrhea. Last night she pooped in my tub and I noticed it was black and stained my tub.I thought maybe she just ate something she was not supposed to but now I am seeing dark stool I looked a little closer and did see a worm.what should I do

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Precious! I think you should take Precious to the Vet today before the weekend. Three days is a long time to be sick and not be better. We don't like cats going more than 3 days with out eating. I would collect a stool sample to bring with you so the Vet can check for intestinal parasites. Causes of vomiting, diarrhea and not eating in an older cat are: kidney and liver failure, diabetes, overactive thyroid (hyperthyroidism), intestinal parasites, pancreatitis, inflammatory bowel disease and cancer. Your Vet, after their exam, will likely do blood work, check her stool for parasites and possibly take an X-ray of her belly. I hope this helps and I wish Precious a speedy recovery!
