So long as the white spots stay powdery and not feel gritty, you have nothing to worry about. Guinea pigs excrete excess calcium in their urine. It’s good you’re feeding a low calcium diet. Do you filter the drinking water especially if you live in a hard water area? A lot of calcium comes from drinking water and too many pelletswe have two pairs of two, so in each cage (there is two separate cages) we give them 1/4 cup of pellets in their conjoined bowl (it is often not eaten all the way, they mostly eat hay). we tend to give them romaine lettuce and cilantro a lot.
As you know, the white spots are the normal way for them to excrete calcium. As long as it is occasional and not gritty then it is not a problem. It’s just normal for piggies to do this.
If it happens a lot then do review the diet.
Most calcium comes into the diet via pellets and drinking water. Ensure you feed just one tablespoon of pellets per pig per day. Pellets should not be a huge part of their diet at all - they only amount to about 5% of the daily food intake.
Also you should ideally filter their drinking water.
Veg wise - safe daily veggies are lettuce, cucumber, bell pepper and cilantro.
High calcium items such as parsley, kale, spinach and sugary/grain items such as carrots and sweet corn should not be fed often.
Do note that reducing calcium too much can can cause as many issues as calcium being too high. You can still see white spots if calcium has gone too low. The balance has been knocked out the wrong way.
