Neighbors, Thank you all so much for your concern, kind words, and advice for our sick bunny! I was amazed at the wonderful response. Thanks to your recommendations we took Linus to a great vet this evening, and it appears he had a stroke. It sounds scary but will be ok, he's on meds and should recover in the next few weeks. He's an older rabbit, and we're told this can just happen with age. Again thank you all so much, I continue to be amazed at the care and helpfulness of this neighborhood! Charity
