It is concerning that Meekah is losing weight rapidly. When a cat eats wet food, more of it is needed to reach their daily caloric needs due to the high moisture content of the food. It could be that you aren't feeding her enough, or she could be suffering from a medical illness causing her to lose weight rapidly such as kidney failure, liver disease, diabetes, hyperthyroidism, or cancer. I would take her into a vet as soon as possible for a physical exam, blood tests, and urinalysis to start. The vet may want to do other tests such as an x-ray or ultrasound to diagnose the cause of her weight loss. Once the cause is diagnosed, the vet can discuss treatment options. Because she is losing weight rapidly, I would take her into a vet immediately, even if it means taking her into an ER vet. Best of luck!
