Pet's info: Cat | Domestic Shorthair | Male | neutered | 10 years and 8 months old | 10 lbs

My cat has had chronic diarrhea and vomiting for a month. He is losing a lot of weight as well. He has been seen several times for these symptoms. Vet ran bloodwork twice and the only abnormal test results was elevated liver enzyme. He however didn't do a fecal flotation. Could my cat have parasites? Is it safe to give drontal tablet that I have been prescribed for him? My vet isn't open today. I don't want to my his symptoms worse.

I would talk to you veterinarian next week about gastrointestinal disease. With a continuously vomiting and diarrhea cat my concerns are Irritable bowel disease or even lymphoma. I would be less inclined it be intestinal parasites if Opie has been an indoor cat. I would not give the drontal today. I would recommend seeing a different veterinarian for a second opinion but Opie may need an abdominal ultrasound. If he is really have bad diarrhea and is still vomiting a lot a specialty hospital may be worth going to because the internist can perform the ultrasound.
