Poor Brodie... and poor you..!
It is weird, but here cats don't have to stay overnight ! Even females may go home same evening! My Inka and Maya were asked to check in with an empty stomach, at 9 am. I was asked to pick them up around 6 pm same day! Of course they were still sleepy and very calm, but I was so happy because I didn't have to spend a night without them! We kept them in our bathroom, just next to our bedroom; so we could check on them during the night. But we didn't have any problems. They weren't even wearing a collar, and they never licked their stitches. Vets use stitches here that don't have to be removed!
