dragn - My bathroom scales are underneath the vanity unit in my ensuite, and only come out when Ram, the wubble's gorgeous Vet, comes round every three months for her Parkworm shot and whatever else is needed at the time.
He has to weigh her to know how much vaccine to draw from the vial, so he weighs himself carrying her, puts her down [much to her dismay, because she lurves him] to weigh himself, then does the maths to work out her weight.
