My rabbit who I’ve had for about 4 years has made a new habit of getting poop stuck to the same back left foot. It’s leading to a bit of a sore foot that has been seen by a vet, but I cannot figure out this behavior. He is healthy, eating and acting normal besides this weird habit. Poop even looks normal. Please help ! He lives in an open, clean environment and has a sibling who never gets poop on her feet. Again, it’s getting stuck to the same foot every time so as I gently remove it with warm water it’s irritating his foot and removing hair.
