One of my cats, a female, had a problem a few years back. She had a problem moving her water (crystals). So, on Vets directions, we had to put her on a special diet, and temporarily monitor how well her water passed. How did we do that? Well, we isolated her and put glass beads in a litter box, and took samples, using a syringe. It is not an understatement to say that she did not take to pee in glass beads. Anyway, we got through that.

Two weeks later, I had to reintroduce the glass beads in the litter box. She did not like it a bit. I took a half-day off work, and isolated her in the bathroom with food and water. After four hours, no go. She would get in the litter box; seem to want to go, only to get out when she saw the glass beads. I was frustrated, as was she. She crossed her legs, refusing to relieve herself in the beads.

Suddenly, I had an idea. I used one of the syringes to pump water into her. I tried it. After ten munites, in desperation, she entered the litter box, and a massive stream of water flowed.

I srynged up the fluid and took the sample bottle to the vet. He looked in amazement and said, "Wow, I have never seen a sample that large from a cat, we normally get a small amount to test, the sample bottle is full. How did you do that?"
