Ouch poor Lulu! It's possible that she is suffering from severe gingivitis, a tooth root infection, or a rotten tooth causing her dental problems. Having severe dental problems would cause her to drool a lot, avoid eating on one side of her mouth, and bleed. I would have her seen by a vet for it. Cats need dental care just like humans, and the way to treat this dental problem would be be a dental cleaning, scaling, and polishing. I would make an appointment for her next week. As for vomiting her food whole, that could be caused by a problem separate from the dental issue, and she should see a vet for that as well.
