You can see my new gorgeous siggy at the Fuzzy-rabbit.com forum. Queenie had a urinary tract infection scare but interestingly it turned out to be behavioral. She would leave a few drops in one area of her board floor only. The vet started with antibio but when that didn't work she suggested covering the are - i put a small litter box over it, which she didn't use, & after a couple weeks no longer peed onher floor. An interesting lesson that some problems are behavioral & not medical. Similarly i cured her gas by providing a cat tunnel & a castle to run into, to provide exercise. The vet had no clue what the problem was even after observing her overnight. Sometimes your own bunny sense may work where the vet fails.
