Our bunny, Misty-Rose, appears to be slightly shaking when in resting mode.  Is this normal?  Is it her form of breathing, or is she actually shaking?  Could my house be too cold from the air conditioner?  Please share your thoughts.

The normally breath at a faster pace then we do, but I would just keep an eye on her, ahe might be stressed because of the new enviornment

My buns loves it cold. He will even sit on the air conditioning vent. He also was slightly shaking and breathing heavily recently. He had just gotten back from the vet and was very stressed. I agree with bullrider that it could be stress.

I have seen both of my buns do this, but it's only been in situations when they've been stressed, such as just after nail clipping. It's like they go to lie down and relax/try to calm themselves.

I'm not sure that it's only from stress, but that has been my experience.

Yes, bunnies do breathe faster than we do, so it can be normal. One of my two often breathes fast and sort of shakes while she does it, but she's not wheezing and I've learned it's normal for her. It's also one of the ways they can cool down (since they don't pant or sweat) so they'll usually do it after running around or when they're hot (stress can also make them hot).

If you think it may be stress, try sitting next to her, pet her gently and speak soothingly. See if her breathing slows down a bit, though I agree that quick breathing is quite normal.

I find sometimes when my buns are laying down after hopping around, they almost look like they are hyperventilating. They breath so much faster than we are used to, 32 to 60 breaths per minute compared to our 12-20 breaths per minute.
