What are other signs of URI? my Nellie started sneezing as the weather got better and we opened the windows. She doesn't sneeze a lot but I notice it happen at least once a day.

I assume it is alergies because she started sneezing just as the season started. I'm afriad to take her to the vet because I hear bad stories about our local vet and I'm a really poor student but I don't want to risk my cat's health even if I have to risk my credit rating
