My cat, Mattie, is 12 years old currently and has been acting a bit strange these past 2 years. She wanders into bathrooms in the middle of the night and yeowls loudly, but when you investigate she seems disinterested in you. I found that she has a habit of drinking from the toilet and assumed that the water in her dish was inadequate. I make it a point to refresh the water dish every time I pass her water bowl. However the yeowling continues. The vets I’ve visited have ruled out blindness and dementia, and simply say shes lonely. I don’t really know how to feel about this as she isn’t a clingy cat. Recently, she has been diagnosed with Kidney Disease, and I was instructed to put her on prescription food (Dry and Wet), and I can’t help but wonder if her midnight caterwauls are due to an illness I can’t see. Is there anything I can do?
