Hugo's There
Wise Old Thumper
My observations have been that for the last 2 days of being on filtered water the amount of calcium has decreased, there is only 1/4 of white stuff in her litter tray, compared with before. We do have very hard water here though its awful...
Sludge is so difficult. You never know if seeing it or not seeing it is good or bad!
If you don't see it or it reduces you can't tell whether it's because there is less sludge in the bladder and if there is, whether it is due to a change in diet or whether what was seen before was all there ever was to come out and not related to any changes. Or if not seeing it or so much of it, means its now building up in the bladder and less is being flushed out.
There is so much guess work involved. For me personally if there was known sludge in the bladder I preferred to see plenty of it coming out, although I always felt bad for bunny as it must hurt
As I mentioned previously fluids is the key so whether it's tap water, filtered water or bottled water just make sure she is still drinking loads and any changes in water type does't lead to a reduction in drinking while she gets use to a different taste. We found that adding probiotics helped increase water consumption as he loved the taste. It also helped boost his immune system as sludge often creates a urinary infection as it irritates the bladder lining.
