Q. My cat is urinating excessively. I took him to Dr. First time he was blocked with crystals. Second time no crystals and nothing on sonogram.
DR. MASSIMO ORIOLES, DVM, MRCVS
A. The cystitis, inflammation of urinary bladder, this time may be idiopathic.
The cystitis needs to be treated anyway as it could cause urinary blockage (through a urethral spasm due to inflammation).
Stress should be limited as much as possible and stressors should be recognised and avoided.
If you like to discuss this problem further I would recommend to take him to your veterinarian or engage in a consultation.
