Wow, that is the website I found a few days ago. She has most of the symptoms listed there.
She doesn’t seem like she’s in pain, more uncomfortable and confused.
I ordered the Tinkle Tonic and am praying that relieves some of her discomfort.
I also layed down some old towels which she seems more comfortable relieving herself, instead of the liter box.
I’m more upset than she is.
The most important thing to manage CRF symptoms is monitoring blood levels and likely administering sub cutaneous fluids. This is hard, but not impossible, if you don't want to take your cat to the vet. She likely has elevated BUN (blood uric nitrogen) and creatinine levels. To bring these levels down and often to see a huge improvement in your companion's energy level and happiness, subQ fluids once or twice a week are a great treatment. You can buy subQ packs from your vet for you to administer at home. The other likely cause of lassitude is anemia and a common drug to increase red blood cell supply is Epogen.
