Glad to hear Rex came though surgery so well. When my little one had lp surgery i had one of the wire kennels (she never used it) I flipped it over and filled it with pillows and that was her recuperation space. I would carry it from room to room so she could always see what was going on. Thankfully my sister was staying with me at the time and she was home with her while I was at work. I used a scarf as well to hold her up when she had to go out to potty. As Yorkiemalt said make sure he takes his medicine on a full stomach. Keep his bandages dry, if I was going out for more than an hour I would put a diaper on her so she would'nt get her bandages wet. Oh and peeing and pooping may be delayed due to the surgery so bear that in mind.
Keep him as quiet as possible, no jumping or walking except for potty time.
Good luck,
J
