find a new vet! the sneezing sounds like she has a cold, so she needs medical care. It could be an allergic reaction to the carefresh too, maybe try using paper towels for awhile or something and see if it clears up. Just because their is no blood doesn't mean it isn't to be taken seriously.
mm I want to take her to the vet I really do but my mom is kind of dumb about this kind of thing and she said that she doesnt want to take 'stupid rat ' to the vet heh.. Maybe i can find another way to get to one.
How much would it cost and what do you think they could do for her?
Like give an injection or something?
