The weight for sure, but the other measurements (body fat, pulse etc.) probably not.

If she keeps still. Otherwise you stand on it and then stand on it again alone. The surface is made of glass, which the cat might not like.

I guess it can also work with animals. Although there is no delta measurement (first human alone, then human with animal, and then animal calculated), it is not necessary to use the sensors for body fat ect. for the weight measurement. My daughter is into it and the app gives her weight very precisely, no other measurements are taken.

So suitcases or boxes from 2-3 kg work, I have never weighed animals!
