Hello,
I am sure that probably hurts a little bit but it doesn't look infected either. As suggested,
you can use raw, unpasteurized honey or antibiotic ointment on that area to help ward
off infection.
Are you using one of those fine, green mesh types of hammocks? A lot of them tend to
get their claws caught in those things. I recommend taking that out & either making one
out of solid material or purchasing one like that. He will like that type just as well.
Let us know how he is doing.
