there’s some kind of goop in my guinea pigs poop? where the red arrow is? this was taken straight after she passed it as i watched her go then thought i’ll just check it make sure it’s looking healthy and saw this? should i be concerned? i checked her over and she seems fine other than her feet (i’ve included photos of them!), she gets foot spurs but i’m not sure if this is maybe bumble foot? any advice would be great! i’m in process of moving but gonna book vet appt for next week.
