Lofdi (the Kamikaze Commando Kitten) took a tumble off of the cat tree tonight and when I went to pick him up later he yowled and scrambled off. When I got him again he had a big lump in his chest so I called the e-vet right away. The x-rays showed that not only did he have a fractured rib (just one, fortunately) but that he had a fractured (or whatever you call it) sternum, which was what was jutting out. He is in no danger and safe, but he is going to spend the night there and the surgeon will look at him tommorow. The ordinary vet says normally they would leave a broken sternum piece in place but this one is jutting out soo badly that she says the surgeon may want it removed. I am so relieved my kitten is safe, but I hope they can do something for his sternum, it is stuck out really bad and must hurt a lot.
