I am so sorry to hear of Maverick's passing. Thank you for giving him such a loving home. It is never easy losing something so precious. (((Hugs))) to you.
Usually excessive drinking and peeing are one of the signs of CRF, so I am surprised Win is NOT drinking! Not eating is not that unusual, and the special kidney diet foods sometimes aren't that appealing to them either. You might want to pay specific attention to this link: http://www.felinecrf.org/persuading_cat_to_eat.htmMy 14-year-old cat, Wintressia, was diagnosed with CRF a few days ago. She's urinating a lot, and she's lost most of her appetite, which is a very drastic change from her usual black-hole eating habits.
Her BUN and creatinine weren't super-high yet, so the vet only recommended the special diet and more available water. She didn't think I needed to start subcutaneous fluids yet, but Win's appetite has been nearly nil the past few days, so I don't know if I should get her started on sub-q fluids anyway.
Her phosphorus isn't in the danger zone and her potassium isn't too low, so overall, I guess we caught the diagnosis early.
My vet clinic is very nice and modern, but every time I make an appointment, I am assigned to see a different vet. There are quite a few vets working there, and it feels like they don't really care which vet sees you, so I've never really felt that any one vet has gotten familiar with Win. I'm thinking about seeing a new vet in a couple of weeks to get a second opinion and give Win a urinalysis again.
Has anyone tried wetting their cat's paws/legs with a little water to encourage them to lick off the liquid and force them to ingest it?
