my 5 month old boar, humbug, seems to have a pinkish colour to his urine. i wasnt sure at first as i thought it could be his droppings staining it. but i cleaned his pigloo today and put in fresh white bedding and noticed tonight that he has passed urine in there and i would definately say it has a pink tinge. he seems perfectly well in himself in every way and i would have no worries about him other than this. should i be taking him to the vets ? any ideas or help would be much appreciated - many thanks
