Our experience was a little different with Miley because she needed an emergency hernia repair about a week before she was scheduled for her spay, and we had to take her to the emerg vet about 3am. They did a combined hernia repair and spay for her so she didnt have to go through two surgeries. We picked her up I think around 4 that afternoon, so she was kept for about 12 hrs. For Miley, she had two incisions and they closed her up differently than they would have had it just been a spay, so she needed to go back after 10 days to get her stitches out. For those 10 days we had to keep her "quiet", Miley is such a wild, active girl that for her that sadly meant mostly cage rest for 10 days. It sucked, but was worth it to get her healed. We were told to take her out to potty on her leash, but I admit that I didnt. We have 2 other chis and a lab, so I made sure to take her out by herself, as normally she and our lab love to run long laps around the yard chasing each other. If Maya is the type to really go nuts in the yard I would keep her on the leash outside just to be safe. We fed Miley on her normal schedule, 2 times a day, and she had some antibiotics and pain meds that she needed to take with her food. Ask them, but I dont see any reason why you couldnt offer her something to eat if youd like when she gets home.
