I don't even know if there is something wrong but here's the scoop: about a month ago, I had my 2 year old cat spayed. Everything went well and she seems much happier. She started eating more which is good cuz she hardly ate anything before. However, she's gotten quite fat rather quickly. Also about 2 weeks ago, I noticed she started wheezing randomly. She doesn't seem to be having trouble breathing - it just sounds weird when she does sometimes. Like she's snoring, but she's not asleep. Other than those two weird things, she's perfectly fine. She runs around, purrs, and eats like normal. Should I even be worried?
