Cat Vomiting, Likely Has Worms

My cat Maisie has been vomiting lately. I didn't think much of it at first because I've been changing their foods. I noticed a few weeks back that she's starting to get a potbelly look and I just thought she was just getting fat, but today she vomited again and I saw a white curly thing in it. I looked it up and it's likely roundworm, which would also explain her potbellied look. I made a vet appointment for her and Remy on Monday morning to get it checked out. Is this something that can wait until then or should I see if there are appointments earlier than that?

Hi! Probably she can hang in there, good on your for taking action!

If my vet had an appointment open i would take them in as soon as possible. However if not then Monday it is. It may take more than one round of treatment to get them over the problem, talk to your vet about that as well. Best of luck to you guys!
