yeah, that is one of the "circumstances" I had in mind
Aggressive behavior is another.
My youngest male is 7 months old and has not yet been neutured.
I plan to allow him his full 9 months, also because he is still quit small.
A few days ago he suddenly grabbed my hand and started biting it.
When I said : He, what ARE you doing? he immediately stopped biting and started licking my hand instead.
If he hadn't I probably would have taken him to the vet the next day.
Chop-chop for you my friend
