Pet's info: Cat | Domestic Shorthair | Male | neutered | 10 years and 6 months old | 19 lbs
What could my cat have? He was screaming and had bloody urine 6 weeks ago. Went to er vet was told he has stress cystitis. Went to reg vet next day and for two weeks did onsior and pain meds. Then he continued to cry in box but was urinating great. Urinalysis showed a uti so started anti biotics for 13 days. Those are done and 2nd urine test showed no infection. Thing is, he's still crying only when urinating once a day. What are we missing that could be wrong with him?

Stress cystitis is VERY common and I agree with the presentation however, if xrays were not done he may have a urinary stone lodged in his urethra causing a blockage (may be partial), pain and discomfort. It is an emergency if he is producing little to no urine!
So, if no xrays have been done I would do that ASAP. If he has not had bloodwork that is imperative as well!
The other thing you may want to try is Feliway which is a product that reduces stress:

Their website is an excellent source of information on how to use this product effectively. It really works wonders!
Finally, be sure you are making the necessary changes in the environment and he may need a special diet like Hill's c/d stress ( you will need to get that from your vet).

Usually is this diagnosis (which by far is the most common cause of feline cystitis) is established by ruling out other causes like urinary crystals or stones and urinary tract infections and possibly even urinary bladder tumors.
X rays and/or abdominal ultrasound, urine analysis are usually performed.
If it stress related the key factors of stress must be understood discussing them and if not removable or found medical treatment for stress can be eventually used.
