They are actually co-existing quite fine. Hershey is young and he's not a dominate personality, so he must come across as less of a threat than Oliver. The indoor boys are a little cautious around Hershey and the girls just hiss, which is how they treat any new kitty.
Hershey really, really wants to play!

Hershey's been trying to get the other cats to play with him, but he hasn't had any luck. He attempts to initiate play by pouncing on the unsuspecting cat, which for some reason only freaks them out! He's not afraid of the cats at all and doesn't seem to understand why the other cats might be so cautious with him.
Hershey's gonna make someone a great cat! If I had a huge house with unlimited funds and time he could join the gang, but since I don't have those things, it wouldn't be fair to the cats who already don't get enough of my time. Hershey will be placed in a good home where he can get all the spoils he deserves.
