We adopted a 7 week old rabbit. Took him to the vet today for a wellness check. Found a reducible lump with the diameter about the size of a quarter. The lump is right below the sternum and you can feel the sternum splits. Vets advice was watch and wait. Eating ok. Drinking ok. Active. The lump is not hard. Vet said it could be nothing or it could be something serious and might want to prepare the kids in case… but only treatment was watch and wait. Cannot find much about a reducible lump/hernia (vet said she was calling it a subcutaneous hernia) below the sternum/ribs. Anyone have any ideas???
