She isn't wheezing or being lethargic, she JUST finished shedding. But she has opened her mouth, or yawned at least 3 times in the 20 minutes I was on a video chat with my wife. (I'm out of state.) She had a bad shed because the tank was a little low on humidity, which I plan on buying an automated humidifier/regulator. But reading online about yawning is scaring me into thinking she has an URI. I'mcalling the vet tomorrow and having my wife take her, but in case I'm just over thinking or being way too worried, what other indicators hint to URI?
