I have 6 cats, all up to date on their vaccinations, and one by one, have started coughing, its kind of like they are trying to cough up a hairball, but its just a dry cough. Does anyone know what this may be?I am going back to the veterinarian on Tuesday with my kitten, who is isolated from the others, he had a really bad URI. He is getting much better! The other ones started this coughing thing. The kitten does not cough so I dont know if they have picked up what he had or if it is something else. What makes me think it may be something else is that the kitten never had a cough, just congestion and URI symptoms. But he is getting so much better now, but I still have him away from the others till he goes back to the vet on Tuesday for a checkup. They seem to feel fine, just that cough a few times a day is the only symptom so far. They are eating and drinking fine and playing.
