I found medical recommendations. Meat and dehydration can lead to development of urine crystals. Recommendation is to drink at least 1,5L of water in cold climate and at least 2L of water in hot climate. The easiest way to control that is by watching color of urine: normal urine is light colored.

Also, meat is recommended to eat with veggies, because of opposite effect on urine acidity. Good to know.
