I have had chronic upper respiratory infections ever since I was born. Last summer we found out I was heatworm antibody positive. Over the last couple months, I have been very congested and the vet has put me on an antibiotic. It was not working, so they put me back on the original medicine I used to take, Clavamox. This has never given me problems in the past. The medicine is working as my congestion is almost gone. But, I have decided not to eat my cat food. Over the last 3 days I have barely had anything to eat or drink. My owners often would give me treats after they gave me the medicine. Now when they try to give me a treat I gag. I will eat their human food, but I will not eat my dry or wet food. When I called the vet, they told me to keep giving her the medicine and to mix human food with the cat food. They tried mixing the foods tonight but I still would not eat the cat food and the treats still make me gag every time they try to give them to me. They have even tried many different flavors of the food. What should my owners do?
