Cats gum is lined red

[mycatisnamedruby]

Hi! So my cat has had problems with throwing up and loose stool. Recently it's gotten better but I've noticed that her gums are lined red. She is only 1 years old. I have spent so much money on her! Do I have to bring her to the vet for this? I have recently started brushing her teeth and giving her dental cat treats... I previously felt bad brushing her teeth because she had big ulcers on her lip. I have attached a picture of her teeth and gums.

She has had mouth ulcers? Was she diagnosed with Feline calicivirus (FCV), Feline herpesvirus-1 (FHV-1),Feline immunodeficiency virus (FIV), or Feline leukemia virus (FeLV)? Or was it feline eosinophilic granuloma? It could be juvenile gingivitis. My boys had that and both did have to get a dental cleaning. Fynn at one, and Jethro at 2. Jethro had stage 2 periodontal disease I would have a vet check her teeth. Most times vets do offer a free dental check
