Cat vomiting clear liquid

Last night out of nowhere our boo threw up a pretty good amount of clear liquid. I cleaned it up and it had no smell at all. After that she threw up a few more times but the amount of vomit was very small. She slept all night and this morning seemed very out of it. She has slowly come back to normal although still a little out of it. She ate. Fancy feast broth and a few treats (she will never be too sick for those!) and kinda played with our other cat a bit. She's much more alert and has been roaming around a little more as usual. She has an appointment at our vet for tomorrow since they're booked for today. Any advice on what to watch out for until then? She hasn't thrown up since around 8:30 this morning. Any advice will be great. She's an indoor cat and eats dry food and a broth on occasion. She's not a fan of wet food. Thanks all!

It's good you are taking her to the vet tomorrow.  It really could be any number of things and she very well may come out of it on her own.  I would feed her whatever she will eat for the rest of today including the treats.  You can also try plain meat baby food, even kitties that aren't big fans of wet food will often eat that.  You want the baby food that doesn't contain onion or garlic and is just meat and broth.

She seems to be a bit better. She has been wandering around and sniffing some things I brought from my parents house. I haven't seen her eat or drink but she has eaten the broth from this morning and treats. She is still sleeping a lot but it isn't too much out of he ordinary. I just want my baby to be her chatty loving self.
