Today I noticed that my pig Sundae's urine looked dark- kind of orangey in colour. She was puttering around outside grazing on the clover and had just peed before I picked her up- the big of pee on her fur looked orangish. She seems otherwise fine- no squeaking while going pee, activity and appetite seem normal. Hard to tell what colour the pee in the cage is, since they are on brown Carefresh and it all soaks in. Does this sound like it could be a UTI? Is there anything I can do at home that will help? The soonest I will be able to get to the vet is Tuesday, since tomorrow is Thanksgiving Monday here in Canada and everything is closed. If she does have a UTI, what is the best antibiotic for treating them? Is there one that works best or has less side effects?
