LOL I understand that concept although I usually get my weight alone first. I don't know if it is because the furkid is so big and I have trouble seeing over him to the weight, but my scale always gives the difference as much more than what the vet has. Morgan spent years on Science Diet Light cat food because we were trying to regulate his weight gain. He gained every single trip to the vet but it was never as much as I anticipated because of weighing him at home. I know that I must have a problem with the process because sometimes it varies a pound or more on different days. While I may gain or lose a pound over a day or two, the difference in my weight and his shouldn't vary like that.
