@Sweetpeaelf:
Roo is jealous of Piper already. He plays rough with her and he is always biting her throat or neck, so I am unable to leave them together. The good thing is he doesnt growl and he has no problem sharing food or toys with her. Hopefully, In time he will adjust.
That it totally normal.. and you really should let them work it out on their own. He is teaching her…
And growling would be normal... and especially sharing food. I would never expect mine to share food.... toys, of course... but not food
