So I called my vet to ask about some odd behavior I've witnessed over the past week or so. My Beansy has been "periscoping" as I call it or climbing an invisible wall then arching back. After he has reached as far out as he can go he goes back down then commences in this little "dance" or something that looks a bit like somebody with Parkinson's but just in the head not his whole body. The vet seemed very concerned and suggest I take the next available ASAP as he sounds as if he could be very ill so I made an appointment for 9 A.M. Is this true? What type of questions do I ask? I've never had so much as a cold in any of my animals. What could cause this? What are his chances?
