Beth: Can you stand on the scales whilst holding them and then again without them to get an idea of their weight?
I could... if i had any
though 'tis a good idea, i'll see if i can borrow some from someone.
I know they are all tiny girls though, the "fosters" weighed in at the rescue vets at a grand total of 2.5kg each
they have both put on a little weight since being with me, but not masses, and were already 18 months - 2 years old so haven't actually grown. Penguin is the smallest of the bunch, she still looks like a kitten compared to the others.
Thanks all for the replies, i'll keep the ones i have and just portion them accordingly.
