Ive had my burm throw up water.. He sprayed it once all over the glass... Not sure why and it only happened that one time...he did some odd movements too, their muscles i assume. Clicking (bubble wrap) sounds like Repository situation... But without any other symptons i dont know....
make sure your uth (if you use one) is not over 91... Ive heard of strange neurological situations from a uth being over 100 degrees under a hide.
If you feel somthings wrong make a vet call tomorrow.
