Hi, one of my guinea pigs (i know which one) has been leaving small spots of blood around the cage. I had them at my friends house for a week while i was away, and she had taken care of them before. i supplied the veggies so i knew what they were eating. when i got them home i started to notice small red spots. Its not like there is blood in her pee, because her pee would be alot more than just a spot. i had her on paper towels for a while to see the blood and it is not diluted much, if at all. I notice she does seem to be in pain when she goes to the bathroom and squeaks and hunches over a bit. whenever she does this all she leaves is the blood and sometimes poo. they eat very healthy diets, oxbow pellets, timothy hay, water and 2 cups of veggies every day, but she is not overweight. she is still eating and drinking but i am getting more worried. i have spent the afternoon calling over 15 different vets near me and none of them take guinea pigs. i will end up taking her soon but want to know in the meantime. it seems like a UTI or Bladder stones but i know that the blood usually comes out in the pee with that. i really dont want her to be in pain. What should i do? putting diluted sugar free cranberry juice in one of their water bottles. i am avoiding calcium rich foods. anything else? and is there anything else it could be? again, taking her to the vet once i find one but need answers for the meantime please
