or:Just a little learning tip for you, since it's been a while since your pet came home. The importance of this is when they're still drowsy. You fast the pet so that there is less chance for them to get sick and choke on the vomit. Once they are no longer drowsy, you're completely in the clear. That's the only thing you had to worry about though, next time you know what it's for!
