hi, i like your avatar! it looks like my piggie.
Hey! I just noticed your thread about possible sludge issues. If the white spot is smooth, then there is no need to worry, it's totally normal. If it is gritty then you are looking at potential stone/sludge issues. If you have any questions PM me, and I can try and help. I have already gone through 1 stone surgery and many UTI treatments with one of my boys.
