We have an Animal Emergency Hospital VERY close to us. 2 miles away at most...
We check the weight on the ladies every 3 days and keep really detailed records. (Made a really cool graph on the laptop! hehehe!

) We ONLY visit this particular Vet to use the scale there and we always compare the readings we get when we take them to their regular Vet and use his scale.
We will record their weight taken at their regular Vet whenever we go and then check them again on the way home using the scale at the Animal Emergency Hospital.
Stuff I have noticed...
Even though we ALWAYS hit the 'zero' button first and ALWAYS make them sit still in the middle of whatever scale we are using at the time, We NEVER get the same numbers from different scales at different places... :no2:
One day, We weighed them at their Vet during an ear appointment, Then weighed them at a different Vet before getting some shots, then weighed them on the way home at the Animal Emergency Hospital (their 'normal' Vet for checking weight...).
We got different numbers at each place that day with a 2 lb max spread between numbers... We ALWAYS hit the zero button and ALWAYS make them sit still in the middle of each scale... Not all scales are accurate. I am SURE of this.
At 14 weeks, The girls are currently gaining between a 1/2 pound to a pound every three days. We will post our graph once they get to @40 or so lbs each...
We give them lots of bread and tortillias as treats to help make their butts bigger...
One girl is an 'inhaler' and one takes her sweet time and LOVES to make a mess. The 'inhaler' has to watch her sister finish her treat and she is NOT allowed to mess with her until she is done. NOT our fault that she didn't take the time to taste her bread any before swallowing it... :no2:
(The 'inhaler' is 'watching' her sister in the lower right corner of this picture... She is NOT allowed to help sister finish her treat.)
