It's perfectly normal for a cat's weight to fluctuate between 80 and 150 grams over the course of a day. This can vary by cat breed and gender. Such weight fluctuations are due to natural bodily processes, such as how often she goes to the bathroom and the amount of food she eats throughout the day. To ensure the accuracy of the data, we perform regular cleansing. More specifically, we automatically clean up any incorrect data every 5 hours, so that by the next day at the latest, the data from the previous day is correct.
