Now we've had a scare with our other cat, Loudmouth. He just went through several minutes of a coughing/reverse-breathing fit. He was treated with a long-acting antibiotic by the vet several days ago for an upper respiratory infection with wheezing. The wheezing is gone, but now we've got this. I don't think we can handle two potentially critical cats.
@leejackson well crap. You need a break.
