We had a much better night last night. Bella only woke up about 3 times coughing and it wasn't nearly as bad - no foam came up this time! YAY! Ripley slept through again. I have noticed now that they mainly hack when they come inside from being out and running around. They have been on the medicine only two days now (4 doses) and they seem to be improving. Thankfully, this is not something my kitties can catch. Whew! This is enough excitement for me!
