Pee? White Pouch?

When my BP pee's one or two little white pouch's come out. What is it? Is it poop? When she poops its not white. Is it normal? My wife never saw it but everytime she pees I see them.

Probably urates: or solid pee. Very much normal.

Urates,it's normal,both my bps do it... Just did some spot cleaning and found all sorts of little gifts today :)

thank you now i don't have to worry
