By Wednesday morning, she couldn't control the urge to pee for more than 2 minutes; it was doing my head in to watch her go back and forth, back and forth, so I made an appointment to see the vet that afternoon. I'd managed to catch a bit of liquid to show them what was worrying me so, but it turned out it wasn't enough to run an adequate analysis on. And because Leila had been emptying her bladder every 2 seconds the entire day, the vet couldn't really feel anything wrong there, either.
Still, she agreed with me that it was not nothing; that her discomfort could be indicative of an infection or even struvite stones, and so she provided me with several packets of diet cat food clearly labelled 'FREE SAMPLES', and charged me 64 euros, 71 eurocents for them.
She also asked me to bring round a bigger urine sample as soon as possible.
Which I did, last night. Don't ask me how I got it; you do not want to know! She put one drop under the microscope (even less of the stuff than I'd brought with me the day before), had a glance, and said: "Struvite stones. That'll be 12 euros 50, please".
I'm in the wrong line of work.
Meanwhile, my cats refuse to touch the diet food. I can't blame them: it looks awfully bland.
