The weight loss is just speculation, he looks slightly thiner but he's always been on the small side (not just thin but small in length and structure). The bulge seems to be the kidney area which is what started my concern but it has gotten smaller the past few days (he'd gone number one and two every day for a few days in a row). I did try the soak and i think it helped (he peed lol) and honestly any excrement at this point I'll take after so many days of nothing. I have a vet appointment for him on Thursday and I relayed all of my concerns to them when I called.
