I am assuming she is favoring wet food because it has more water in it and she is having a medical problem causing her dehydration. this could be caused by diabetes for example, but there could be other causes to that such as a chronic urinary condition. she needs to get to the vet as diagnosis in her condition is the key, she will need a blood test, i believe it should revile the problem.

Sometimes a cat will switch to wet food if their mouth hurts. Attempting to crush the dry food causes discomfort. The excessive urination is an issue. This could be a sign of diabetes and kidney disease most commonly but other issues as well. Have your vet check her mouth and do some routine bloodwork with a urinalysis.

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!

Every pet is different. Some drink a lot of water and some do not. Dry food has less moisture so cats who eat dry food do you need to drink more water than cats who eat canned food. The only way to know if everything is normal is to have her kidneys and urine checked. You may call the rescue group and ask if this was done and if the results were normal. I hope this helps.
