Just arrived home from the emergency vet. All's well
Went w/ my gut as didn't feel right doing nothing... They induced and it was out w/in minutes. It had bloated and looked so big. VERY relieved. He was a bit queasy for an hour or so, but is already back to normal (got home and greeted his brother and is now sacked out on my lap). What a night - so glad my furbaby is okay.
Thanks for the advice and good vibes.
