Hello LaVon, and thanks for requesting me to answer your question about Bella.
I'm assuming Bella is spayed. If not, she may have developed a serious uterine infection called pyometra. Here is more information: Pyometra
If she is spayed, we don't have to worry about this.
From your description of her symptoms, it sounds like Bella may be ill and/or in pain. Not eating, even for a short period of time, can lead to a serious liver condition called hepatic lipidosis. Not drinking, will result in dehydration, which is also very serious. You mentioned she has not used the litterbox, so this may be a result of not eating/drinking, or she may have a urinary or intestinal blockage which can only be diagnosed and treated by the vet.
If Bella is pawing at her mouth, she may have an abscessed tooth, infected gums, sores in her mouth, something stuck on the roof of her mouth or under her tongue, or something stuck between cheek and gum or between teeth. If she likes to play with string-like items like ribbon, sewing thread, dental floss, etc., she may have ingested this and it is wrapped around the back of her tongue. It would be a good idea to try to get a look inside her mouth, but if she is in pain and will not allow you to do this, you don't want to get bitten, so at this point, your next best step is to have her evaluated in person by a vet.
It's also possible that she ingested a toxic or other non-food item, and this is causing her discomfort. She might have chemical or electrical burns inside her mouth or lips if she chewed on something she shouldn't have. If you have any houseplants or flowers, she may have nibbled on those. Many plants are toxic to housecats.
Once she is seen by the vet, she will be diagnosed, treated, and feeling more comfortable. If your regular vet is closed for the day and has no emergency hours, bring her to the nearest ER vet center for assessment and treatment. If you need help finding your nearest ER vet center, I would be happy to help you; just provide your city, state and zipcode.
I hope all will be well with Bella once she is seen by the vet and the cause of her problem is diagnosed and then, treated. Please let me know the vet's findings, if you are able, as I'm concerned for her. Thanks!
