Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. It is very hard to see on the attached x-ray if there is any problem with the urinary tract or. Some of the bladder stones come up on a plain x-ray and can be easily seen. I cannot see any obvious stone obstructing the bladder / urethra. However, some stones are radiolucent (do not come up on x-rays) and the cat would need a constrast x-ray or ultrsound of the bladder to detect them. In general, urethral blockage in young female cats are very uncommon. If Marshy is able to pass urine, other urinary tract diseases should be investigated. Urine analysis should be the next step of investigation (to rule in/out infection or bladder crystals) followed by an ultrasound of the abdomen and a blood test.
