One of my girls is coughing off and on. When we first got them home, Bella was coughing every once in a while, but seems to have gotten over it as I haven't heard her cough in weeks. Fleur, however, is coughing for a couple minutes a few times a day. She is eating, drinking, and is perfectly active, just has a cough. Should I try getting a vet to see her or is there something I can do at home for it? It doesn't seem to be very bad, but she has had this cough for a couple weeks now and while it isn't getting worse, it doesn't seem to be getting better either.
