Questions I asked the vet before Cappuccino's surgery

Cappuccino needed a surgery for a lump on his side. The vet said it is most likely fatty but they want to check. I was so scared, he is 6 and a half and I never had him under general anesthesia before. I asked how the anesthesia works and if they check blood first. They did, and his kidney number was a bit high so they changed the medicine. I also asked if he will need a cone and for how long, when he can eat and drink again, what signs of trouble I should watch for at home, and who I can call at night if something is wrong. The vet was very patient and answered all of it, she did not rush me. I think it is ok to ask a lot. Cappuccino came home the same day and slept on my bed with the cone, he looked very annoyed haha.
