Hello,
I cannot answer this question other than saying if he isn’t doing well you should recheck with your vet. I do thee following for my UO kitties. Pain meds; zorbium and gabapentin. Antibiotic: usually convenia and I teach families how to give sq fluids at home. I also teach them how to palate the bladder and put them on a canned urinary prescription diet.
Of the bloody urine persists take an Xray to look for a stone or an ultrasound to look for abnormalities in the bladder.
Good luck.
Hello,
You can bring a fecal sample to your vet. They should be able to help.
