noob question II

i got a few hard-to-answer question:
1.why did art accept kat as a housemate?(same question goes to pip and that naked squirrel ).why? if i were art, i would not let them stay.
2.if kat REALLY had a feeling for art. isn't that very odd? they will breed new kind of species if they marry.

there were so many question stuffed in my mind. but for this day, this is couple of em'.

What are you talking about? Art, Kat and Pip are roommates and they share a house they pay fair share amount as far as I know.

+ Kat, Art and Pip are best friends and they care for each other, same way they do for Leonard and Scarlet and the rest of the squirells. What will they do kick them out?....not very moral person you are...
