Cat Urine Tester / Pet detector

Cat Urine Tester
Cat Urine Tester

The condition of the cat’s kidneys can be reflected by the changes in the pH value in the urine. By measuring the pH scale of the cat’s daily urine, it can be known whether the pet cat’s kidneys are healthy. The design also focus on the emotional interface, allowing pet owners to see the cat's kidney health more intuitively.
