I went to see bunny today that someone posted on craigslist. First time bunny owner here so I went in with a checklist thanks to some sweet Rabbit Talk friends who gave me a heads up on what to ask He looked healthy overall, eyes looked bright no drainage, ears were clean, teeth and toe nails looked great, but his rear end had some stains maybe from urine or feces, I don't know. I'm leaning towards passing on this guy because I've read that this can indicate something else going on. What are your thoughts?
