Awwww my poor furnieces..Don't worry they will do just great. I personally would talk to the vet more about Cali's procedures. I think adding the rabies shot might be a bit too much. She will be so groggy from the surgery anyway and most of the little ones end up having reactions to the rabies shot. Just something to discuss with the vet, because it might be better to get her the rabies shot later. That's what my vet had recommended for Coco and she was about Cali's size when I got her spayed. Have no fear, the girls will do great
