Yeah, like I said, I merely suspect that the Scale S and app are fudging the numbers a bit because these cats really are close in size, but I wouldn’t expect them to be exactly the same week after week. When a previous (smaller by a few pounds) cat lived here, the weights were always different, as expected. I haven’t tried pulling in a different scale for comparison, so I’m reporting only a guess based on my own limited observations and @carverofchoice’s commentary.
A cool thing about Pet Mode is that the app allows you to designate which pet you just weighed, so you can actually keep historical data for several pets and give each its own profile within the app, and that data is included if you do an export (where Wyze servers will generate an e-mail message to you with a workbook attachment).
