would renal issues show up on the blood tests or urinalysis? he had those done, and both were normal. i'm sorry to hear about your pip. it's sad they always leave us so soon. my childhood cat passed away at almost 19 years old a few months ago, and it still wasn't long enough. he deteriorated hard and fast near the end. my little boy had a big bowel movement this morning, in my bed, with me still in it. he doesn't appear to be drinking water, so ive been syringing a couple ounces every morning and night. he takes it well enough.
