Hello, lately I have noticed that my cat has been gagging almost as if she has a hairball. She has been gagging AT LEAST everyday and it was starting to concern me. Over the past few days I have noticed that she has not been eating or drinking. I even tried giving her tuna (her favorite food) but she still refused to eat it, she would only lick the water around it. Nor has she been using the litter box. I am getting very worried and she has also lost about 3 pounds and she barely even moves. She is about 9 years old so she's pretty old, do you think she's dying of old age? I also can't drive her to the vet because I am underage, and my parents just think it's a hairball lodged in her throat, but I do not think that's the case. Anything would help, thanks. (Please answer as soon as possible)
