I have a digital scale that weighs to the nearest gram - it's one of those with a platform. I just put a plastic food container on top, zero the scale and place kitten in the container. Very quick and easy

I think mine came from Argos, but you can get them almost anywhere.

It's preferable to weigh in grams rathern than ounces as the numbers are bigger and you can more easily see a trend. Kittens should gain at least 10-15g per day.
