A. Weight loss in an older cat is always a concern - I would need a full history to investigate other signs and to identify a number of scenarios: food/calories not being consumed; food/calories not being absorbed through gut; food/calories being used up too quickly? I would always recommend a blood and urine panel (kidney disease, hormonal/metabolic conditions such as thyroid disease or diabetes), a full dental health check (under sedation if the lab work is clear) to identify any underlying factors; if all are clear I would then look at imaging of the gut to identify any reasons such as inflammatory bowel disease or thickening of the bowel wall reducing her digestive capacity or even tumors which may be draining her of energy reserves. If you feel the cat is not receiving appropriate care you should seek referral to an internist or a second opinion
