About two months ago we lost Professor Plum to a URI. Then last weekend we noticed that we could now hear Colonel Mustart breathing and he was sneezy and had a snotty nose so we took him to the vet and was given Baytril to put in his water as he has been eating and drinking normally. He also was given a shot of the antibiotic at the vet's office. It originally seemed as if Colonel Mustard was doing a lot better, but I have started to notice the breathing noises again from time to time and he is still sneezing. While he has two more days of the treatment, I was just wondering how I know if he is really getting better? He is still eating and drinking and can be somewhat fiesty--i.e. flipping his house for attention, so I don't believe he is getting worse, but I am concerned that he isn't getting better.
