Sigh. Bad ending. 3 weeks after the first vet visit and frequent soaking, still refused to feed nor poop. Went to a 2nd vet, immediately got 1 lump out but another lump was still inside so asked to soak daily. Reached home and my boy died. Guess it was too weak for the stress after going off-feed 2 months for the little guy. Blame myself for going to get a 2nd opinion too late.
