It sounds like you're doing everything you can and you're in good hands here with
@Piggies&buns
Not every pig that does white powdery wees will go on to develop problems... it really is something very common. We try to keep an eye on it but we can't 'cure' something that's part of their biochemistry. Because their teeth are always growing they've evolved to absorb pretty much all the calcium from their gut and excrete the excess out through the pee... quite different to us people with our boring static teeth. If pee does get a lot of calcium a piggy might struggle to pass some of the lumps but that doesn't mean a stone has formed. You're doing all the right things.
Cats with an IC diagnosis apparently benefit a great deal from a daily routine they can rely on... a vet was telling me about IC cats in a cattery where they changed the routine and it triggered flare-ups in a number of cats all at once! I don't know how effective that is for pigs - I
do know that George squeaks me awake at pretty much the same time every day for his morning salads! But I expect that will become earlier and earlier as the sun rises
Speaking of sun we are currently taking old George outside on a fleece under a heatpad for 20 mins each day to have an al fresco brunch. My pigs get fresh grass brought in (which they love) but it's too cold for them to run around and there is only mud out the back right now. But I wanted to get a little sunshine on him to help his vitamin D levels. I don't know how this affects calcium absorption but I know it
does affect it somehow. Windows stop the important bit of UV getting through (unless you open them!) We can't really give vit D supplements to pigs. But I wonder whether a bit of outdoor time everyday (keep them warm!) will affect the milkiness of the pee? It might, it might not. But taking a cuppa out for yourself and getting a bit of fresh air with them might help your anxiety too... it helps me to think that I'm trying
something. Take care x
