I always do a course of Baytril for surgeries. Usually I try and have them on it a few days before and try to even it out to somewhere around 14 days.
Metacam after surgery is totally acceptable, IMO. Just make sure if your vet used any before or after the surgeries. I believe some vets, like Dr. Munn, give a shot with surgeries, and so the rat is covered for the first 24hrs. My vets doesn't do such things, so I dosed my girls for 2-4 days after their spays. When they stop doing the owie stretches, I taper off the pain meds. You want to keep it to a lower dosage, so a drop or two would be fine.
And YAY good surgeries!! :happydance:
