Chicken is sort of restless tonight. He is laying on me under his blankets and just seems anxious, he's cleaning himself and sort of jumpy at noises. Yawning more than usual. I can hear him breathing too, it's quiet and doesn't sound wet or rattling, just a soft wheeze on inhalation. His respiratory rate is 30-34 at rest. He's eating well still. So for those of you that have had cats who had HCM and went into congestive heart failure and passed what sort of things were you seeing in the weeks, days and hours leading up? This is a morbid thread I know...but I just am trying to get a picture of what may happen so I know and a timeline of experiences from other cat parents who have went through this.
