As dogs and cats get older they may suffer from bladder weakness and this often occurs in older spayed females. It causes them to pass urine more frequently, often in small quantities. Sometimes they are unaware of it and this often occurs when they are asleep. This can be distressing for both the animal and the owner. Mixed Vegetables tablets are a gentle diuretic which help to maintain the urinary flow, ensure that the bladder is emptied completely when the animal urinates and so will usually improve the situation when given daily at a maintenance dose and so make the animal more comfortable.
