I put Morla outside today and noticed that her urine is a milky white color...could this be from the spineless prickly pear cactus i have been giving her. She loves it and eats it right up so i have been giving it to her every day for the past few days. Is this ok? She is eating well as usual and she has weighed in at 283g, so she is gaining weight every week. any ideas....should i worry?
