I found no toys with sharp or rough edges, so how it happened is still a mystery. What I did was soak some kitchen paper in the saline solution, and line the bottom of his travel cage with it. I got him into a coffee cup filled with treats and put him In the travel cage for 5 minutes. What looked like a really big wound turned out to be a tiny little cut, that had just bled a lot and made it look much worse.
Thanks so much for your help
