As usual, Bob C's advice is just wonderful.  I am saving it for future
reference.  Being a lab tech (human type), I agree with his remarks about
weighing urine and recording weight and output when they are sick - my
vet really appreciates my careful records - she can base her decisions
on facts, not guesses.  I would like to mention a great digital scale I
found at Walmart two years ago - I just love it, it is perfect for my
fuzzies.  The brand name is "Good Cook" and it is only 5 1/2 by 9 1/2
inches - sounds small, but I have weighed a dozen ferrets in it, and they
fit just fine.  It "tares", and weighs in lbs/oz. or grams/kg, up to 5
lb 4 oz.  (2400 g), and was only about $30 !!!  I have compared it to my
vet's scale (weigh 'em at home then at the vet's) and it is right on the
money.  It uses a 9 volt battery.  The tray is easily removed to clean.
A dab of Nutri-cal or a few drops of Ferretone keeps them in it and still
enough to get their weight.  The manufacturer is Bradshaw International,
out of Rancho Cucamonga, Ca, 91730 (and yes, it is a real place in
Calif.) ....
