I currently have a 8-9 month old boar, his brother recently had stones ( vet said that it was a genetic thing as I feed them hay, veggies barely any pellets or treat, daily vitamin c supplement (oxbow), nothing that could of caused stones at such a young age) and I. Am now worried for him. He doesn’t drink much water (despite my best effort, he won’t seem to want to drink from the bottle... - I thought it was maybe the taste of the water so I started filtering the water and still no luck, although I suppose the veggies give him enough water to pee) and i noticed that his pee dries a brownish colour (nothing too dark, whereas his brother with stones had clearly blood in his pee when I took him in) so I’m a little paranoid and alarmed that this may be a warning sign. He seems overall well, eats, sleeps doesn’t cry when goes to the bathroom (that I've noticed anyway)... but has anyone noticed this with the perfectly normal healthy piggies? Looking for some advice... I’ve attached a picture of the dry bedding, taken in natural light for some perspective... also, any clues on why he won’t drink any water? Any tips on how to make him drink more water if it’s a problem?
