Thank you Slick , i found that article interesting, as my lexie has the struvite stones, and is on a special diet, but i feed her little and often,would appear that bigger feeds is a better option, she does have plenty of water and seems to drink often enough,but reading how to make her drink more often was indeed helpful, thanks again, much appreciated. ,Also glad i have reduced her food intake, to loose weight, eating too much is also a bad thing for it.
