Evelyn, I'm so sorry to hear you're in the hospital and are worried about where your cat is, at this time.
Is there any friend, neighbor, relative you can call, to pick up your cat and bring her to an ER vet, if she needs medical attention?
If not (to the above) you can call all cat rescue organizations in your area, the ASPCA, Humane Society (if they are no-kill shelters) and ask for help. You can call your city's Animal Control and see if they can help you (make sure they are no-kill, also). It doesn't make it any easier because it's a weekend. Call your vet, if they have emergency hours and ask them for help and/or call you several ER vet centers in your area and ask for their help.
Those are the suggestions I can give you for now, and I hope you're able to get your cat out of harm's way and you will also be well!
Please be so kind as to rate my answer with positive feedback, as that is the only way I receive recognition from the website for my assistance. Thank you very much!
