Hello, I got a new rat named Zeus about a week ago from pets unlimited (this was my first time buying a rat at a chain pet-store). When I bought her, she had to be held at the store for a couple extra days to be treated for mites, but other than that, she had no health issues. This morning, I awoke hearing odd squeaking noises coming from their cage. Taking Zeus out of her hammock, I noticed a strange swelling on her right cheek. The left side of her face seems normal, but the other side of her face is red and swelled. She's been sneezing all day and I can't take her to the vet because of the road conditions/weather. I urgently need advice on what to do, I'm 70% sure it's a respiratory problem but I can never be sure. So far I put her into a separate box with a clean fleece blanket, fresh water and, food. Luckily, her behaviour is normal and she's not acting sick.
