My picky cat is losing weight and has hairballs. Should I see a vet?

Hi! It does concern me that Myla has lost a noticeable amount of weight over the past few months. It's certainly possible that this could be due to her picky eating habits, but I wouldn't necessarily expect her to lose a considerable amount of weight from that alone since I'm assuming that she's always been a bit picky. Other causes of weight loss can include inflammatory bowel disease, a heavy burden of parasites, cancer, kidney disease, or diabetes, although we often see other changes associated with many of these conditions. I do think it would be best to take Myla to her vet for an exam and some diagnostic testing (blood work and/or imaging - x-rays or ultrasound) to try to get to the bottom of this situation. Until her appointment, try feeding her wet food in a room away from your other two cats so that you can more accurately see exactly how much she's eating. I hope that everything goes well!
