Hi there,
Sorry if I am not following, but it is important to restrict her space and prevent her from jumping up on things while her spay heals. Most vets will have buns on cage rest for 10-14 days after spaying.
It is important that she eats. I don’t quite follow from your post whether she is eating on her own, but if she isn’t, you need to syringe feed her critical care or pellet mash. Did your vet give you pain medication for her?
It is normal for there to be behavior changes for up to 4-6 weeks after spaying as her hormones settle down. Most important for now is to make sure she heals correctly and keeps eating and pooping. The spay surgery is pretty invasive so she needs extra care.
