My cat has dry cough, vomiting, diarrhea, and can't eat. What's wrong?

Updated On September 23rd, 2025

My cat has a dry cough. No cold. Wants to eat grass. Vomiting a lot, diarrhea. The cough is now making it hard for him to eat. He will be sleeping and start coughing. I have been administering Petromalt (thinking it's a hairball). He seems to be getting worse. Any suggestions?

While a hairball could cause vomiting I wouldn't expect diarrhea or coughing. A true cough can be a sign of asthma or a respiratory infection. If he can't rest at night and his appetite is affected I'd recommend making an appointment with your veterinarian. They may recommend an x-ray of his chest and abdomen.
