Sending get well soon vibes for your girls, I'm sure they will be fine.
Make sure the vets give you some pain relief to take home, and they won't be able to control their body temperature after the GA so you may need to keep them warm and snuggly when they come home - I'm sure you would anyway but my vet didn't tell me this after I took my girl in, and I put her back outside in her hutch thinking she would be more comfortable in her own surroundings, it was march but still quite cold and looking back I could have lost her because of this.
