It can be very worrying when you notice your cat to start to lose weight, especially if they’re an older cat. Weight loss conjures up terrible thoughts and googling often makes things worse - a symptom as vague as weight loss can mean so many different things it’s bound to be a scary page of results. We tend to notice problems in cats slowly. They’re masters at hiding signs of illness and disease and often live very independent lifestyles, some even going for several days without being seen. The fact that most cats toilet outdoors, unaccompanied, means that you may not notice symptoms such as diarrhoea or producing large volumes of urine. And since many cats have dried food down all day, changes in appetite can be hard to spot at first. This means that weight loss is often the first symptom that people notice in their cats, with other symptoms only coming after you start to keep a closer eye.
