Hi Lisa,
Just checking in on you and Cass! Looks like he is doing great. I saw your post in Health regarding Benny-- the BUN and CRT you posted did not look bad to me. I had a CRF cat, prior to Kitty, and have too much experience dealing with it! If Benny's labs deteriorate and you determine he is a Kidney cat, please let me know if I can offer you any assitance. But, at this point, Benny just looks like an aging cat to me!
Keep up the good work with Cass!
Kim
