There are no "home cures" for this. Your cat needs to be examined, diagnosed and treated by a vet. If finances are an issue, most vets will work with you on payments. This retention could be due to kidney failure, or a disease called FIP (feline infectious peritonitis). The cat's leg can be painful and swollen and cause her to limp and will also cause a complete change in personality due to the pain of the affected leg. You should not treat her yourself or give her any medications without the express consent of a vet.
