<human>:  How can I tell if my cat is unhealthy?
<bot>: One way to tell if your cat is unhealthy is to look for any changes in its behavior or physical appearance. Changes such as less activity, weight loss, vomiting, drinking more water, changes in appetite, changes in bathroom habits, and changes in coat appearance can all be signs of an unhealthy cat. Other signs include coughing, excessive grooming, difficulty with mobility, and abscesses. It is important to take your cat to the vet if you see any of these changes.
