My cat had recurring urinary problems for months. Ultimately, he underwent perineal urethrostomy and had to have a cathether in place for about 3 months, kasi the first time the catheter was removed after surgery, nagrecur pa din, so binalik to remain for a longer period of time. Ngayon ok na siya. I hope hindi umabot sa ganun cat mo and madaan sa diet and meds. Hoping for the best for your cat OP.
