I had quite a long internet conversation with some of the people who work at Best Friends about caring for an incontinent cat and some of that is relevant to this thread. With those cats, because the urine is running through and sitting in areas where it would not normally, it can cause scald and so they give "butt washes" at intervals depending on the cat - once a day, a few times a week, or whatever. The cats that get UTI's are those who are incontinent because they never clear their bladder of urine. There is always a little sitting in there, providing a safe haven for bacteria to build up - even though these cats have their bladders expressed a few times a day (and the mild trauma of that also increases a UTI risk). Since Peanut is urinating normally, although not in the right places, it sounds like she is clearing her bladder so her risk of a UTI is not great. However, Debbie may have to give "butt washes" to prevent skin problems. That should make for even more interesting photo opportunities!
