Tiramisu has been acting constipated since yesterday. He scoots around on his bum and his stool yesterday was hard and dry. This morning, he threw up and didn't eat breakfast; and just now I see that he has what looks like a blister, or pink bubble, on top of his anus. Could that be caused by constipation, or something else?
Should I try giving him some mineral oil?
