I see this is an old thread, but my Schuyler was just diagnosed with CRF and I thought I'd see if there was a thread about others dealing with this diagnosis among Pettalkers.

I found the website www.felinecrf.com (mentioned in a previous post) to be very thorough, addressing all the issues pertaining to the cat, and the cat's caregiver(s). It truly enlightened me and has been a source of knowledge and inspiration. So, please visit that website and it will give you encouragement to help Honey have a good quality life despite CRF.
