I'm taking Sky to the vet this morning at 10:45am. I'm hoping that it's only a bad case of allergies. I've noticed that Sky and Sunny both tend to have sneezing attacks at times so I try not to worry too much. This time it's lingering and he sounds so stuffy. I hope the vet can give me something to make him more comfortable. Thanks again for all of your concerns.
Jazzcat, Sky did have a bad URI before I adopted him so I don't know if it's another flare up or not.
