They're being taken to the vet for their vaccination tomorrow, so she will check it then too.
I think I may have figured out where he scraped it though. The boys have found a hidey spot under the water barrel stand, but they had to dig to gain access. I suspect that whilst digging, Banjo has repeated scraped himself against the plastic without realising
Just a quick update. Vet thinks it is a scrape, not a scratch or bite. He has given antiseptic cream for me to apply twice daily for a week, but said it will heal up fine, although it may take a few weeks to do so.
They are a healthy weight, and he was very happy with them.
They in turn seemed to like him and absolutely loved the car journey. Maybe, like me, they love listening to 80s pop music lol
Oh, and I blocked off their hidey hole - not because it bothered me, but because, even though they finally created a nice route to it, I can't risk further injury if they couldn't quite get to where they wanted to get to in the future.
