My daughter's cat has the same diagnosis. I am so worried about the cat because he has been having serious problems voiding urine for 1 month. However both Vets she took the cat to are not very concerned that he still has blood in his urine at times and sometimes he only urintes a tiny spot...like today so far. I have had many cats that had difficulty urinating and crystals in their urine but none of them took this long to get better. If the cat was having steady improvement with his urination I would feel more positive. I rescued my daughter's cat 1 year ago then adopted him to her. "Bo" is a young,2 year old,neutered,male cat. I am an animal rescuer. I am very emotionally attached to him. Best wishes with your kitty! I'm sure you are feeling emotional also at this difficult time also.
