Of lionesses in heat and when I click on the buyout button, the popup box shows, when I click on the I'm Sure button, the next thing I see is You Have No More Room for Lionesses...How do I fix that?

So here is my player info:
Name: Good Natured Akher01
Player #: 361014
Level: 6 Branch: None! Create?
Stats:70. Territory: 10 (+)
Lionesses: 6. Beetle Slots: 6/6 (+)
Cubs: 10/50. Grandpaw: -
Males: 0/0 (+). Sub Males: None!
Frozen: 0/1 (+). Caves: 3/3 (+)

So what more do I need to do to make the room for more lionesses? How much more territory do I need? How many lions can be assigned to/put in one of those "territory squares" before it gets to be "too crowded"? Might it help if I sort my lions some more and shift them around?

I've been reading the Wiki but haven't found the answer to my questions....Maybe I'm not looking in the right place? I dunno...

Help a girl out? Please and thank you.
