My cat is very sick with diarrhea & vomiting. No vet. What to do?
Hi, thanks for using PetCoach!
I am so sorry that Max is sick! We are not legally allow to prescribe medications because we are unable to examine the pets, which is required to have a client-veterinary-patient relationship. A week is a long time to be sick. Causes of vomiting and diarrhea are: intestinal parasites, viral or bacterial infections, he ate something gross. he has something stuck (blockage), pancreatitis, inflammatory bowel disease, food allergy/intolerance, reaction to new food/treat/table food.
In an ideal work Max needs a Vet exam, a fecal test for worms and X-rays of his belly. If that is fine then I would deworm him, start an anti-nausea like cerenia (veterinary only) or metoclopramide for the vomiting, metronidazole for the diarrhea and put him on a commercial intestinal diet like Hill's i/d until his stools are normal. If you truly have no access to a Vet. I would deworm him with pyrantel or drontal, change his cat food protein source (chicken to beef or fish to chicken), and start a probiotic like Purina Fortiflora.
I wish you the best!
