I have noticed this on two days, about a week or so apart. On those mornings I heard my rabbit make a weird sound, similar to someone trying to cough something up—pretty identical to the cat hairball sound. On both days he made the sound intermittently, starting once every 10 minutes, then going to roughly once in an hour, and then disappearing. So now today it has occurred for the second time. I am hesitant to take him to a vet unless absolutely necessary because the last time a vet visit brought on stasis.
I do not believe these are sneezes, I have heard him do that before and it’s different. Doesn’t seem like a hiccup either. So I am guessing it’s a choking type noise, like something is stuck or aggravating his airway?
The only possibility I can think of is in the evenings I let him graze in a big hay box. He frequently digs a hole and buries his head down into the bottom of the hay box because he seems to like those tiny pieces. This is of course also where the hay dust settles. Could this be causing the problem? The thing is he has done this for two years and I have never noticed the problem before, so I don’t know why it would happen now. All else seems normal—he is eating good, no eye or nose discharge, and activity level is his usual. Any advice appreciated cause I am getting worried, thank you.
