Yes please Lynx. I hope from the comparison they can see the difference having a cavy savvy vet can make. It's taken a year, but now that I've found one only an hour away, I feel a lot more confident about caring for the girls properly.
Snowy update - she's been on dark blue fleece while on her mini break. I gave it a good check over for powder, and there's none! She had a few really powdery deposits last week, but over this weekend they seem to have reduced dramatically.
Just in case anyone is trying to sift through all of the info, here's Snowy's current diet and meds.
6 burgess pellets per dish per feed
Dried Tomato flakes, pepper flakes, dried beetroot flakes, flaked peas (100g of each in mix, 1 tbsp per pig per feed)
Leafy lettuce
Cucumber
Pepper
Occasional tomato
Occasional blueberry or other low calcium fruit
Britta filtered water (my water supply is soft water)
20mg Potassium Citrate EP, twice daily.
1/4 Feline Urinary Support supplement twice daily

0.15cc metacam once a day
For the potassium citrate, we mix one level teaspoon with the same amount of water until fully dissolved, and draw 0.02cc into a syringe to get 0.02g or 20mg.
I've been reading the stone study thread, and the bacteria mentioned in the report is the same as Snowy's culture grew last year.
The lovely Foster Daddy who has been looking after the girls this weekend is the person who can test the stone for me. I've said Oxilates and Carbonates. Is there anything else of interest we should look for? My guess would be that it's calcium oxilate.
