This is not really bladder sludge – I’ve had many rabbits with true bladder sludge and it’s very pasty and thick. White urine is normal.
Nowadays most vets do not think that diet alone has much to do with bladder sludge either. They think it’s more metabolic rather than diet related. However I do think that many of them think that alfalfa based pellets are not good because of higher calcium alot moreso than vegetables which have plenty of water to dilute any calcium. But like I said and if you read the article on HRS, diet alone is not truly the culprit…this is hugely misunderstood by rabbit owenrs.
Most bladder sludge rabbits are usually older rabbits who have arthritis or some sort of mobility problem. It seems to be that most of my true bladder sludge rabbits were also larger. Most rabbits with true bladder sludge will posture and truly have problems urinating and have urine scald. And all my rabbits eat the same thing (exept some get no pellets) so I think it’s more likely genetic, size, lack of exercise, etc…moreso than the diet.
