I'm so sorry to hear he's freaking out, but it is to be expected IMO! I'd let him be in an area that he's comfortable feeling in for the night. Between the surgery, and the drugs he's on, he's going to be agitated, and unsure of his suroundings. It's major surgery that Grady went through, and it's not uncommon for him to freak out. Keep up the pain meds!! Georgie was worse.
