My cat is really sick. She started puking this morning and has been puking off and on all day, and just now she puked up a bunch of clear mucus. She's also been really lethargic and completely unlike herself. I'm getting worried, but my only option would be to take her to the animal hospital, since my vet is closed on Sundays.
What do you think I should do? Watch her and wait until tomorrow, or take her to the animal hospital now?
