Dear friend,
As cats age their kidneys work less effiently (like ours) and the may feel dehydrated. Tha leads to extra drinking because the kidneys may not be dispursing all the fluids to her bloodstream. When a cat has stress - it weakens the immune system and allows infections to take hold. At her age excesss drinking can also be a sign of diabetes.
You can help by making sure she drinks a lot to keep her kidneys flushed. Even add water to her canned food. A few drops of fish oil daily improve kidney function. Also, give her one drop a day of unsweetened cranberry juice to lower the PH of her urine and keep her from developing UTI's.
Please let me know if you have any further questions. I am happy to help.
Very sincerely,
Terri
