Yesterday I noticed she was sneezing. I had her quarantined in a pet carrier (only extra "cage" I have to quarantine her) in my bathroom so I could keep a close eye on her. Anyway, she was sneezing occasionally. I thought it might be the straw in the carrier or something, I didn't notice any white snot and her front legs/paws looked clean. I wanted to get her out of the carrier so she could have more room, so I cleaned out an old wood/wire pen I had built and put her in that, away from my other rabbits. I was watching her from a distance to see how she did in it when I noticed her sneezing a lot and her nose looked white. I checked her out and it's white snot and her front legs are matted.
I'm pretty upset about it. If it is snuffles (I shouldn't say IF, isn't white snot a sure sign?), what are the odds that the previous owner was selling her knowing that she had it? I was going to email the guy to let him know, just in case he didn't. Should I just cull her now and get it over with? She is possibly pregnant, could I wait a couple weeks to see if she has any, and would they end up getting it from her? Or would she be suffering too much? I'm really, really new to rabbits so any advice would be helpful.
*Edited to add, when I went to pick her up, she had no snot and her front legs looked perfectly clean, and no sneezing. That was just 2 days ago. Could the stress of moving to a new place have brought this on?*
