Prelude : Frannie is 13 months old , Spayed had her first
Waffles 3 yrs old, not spayed
set up as in picture -
the xpen comes down and 
Frannie can run around - she will sniff and bunny flop next to Waffles cage for hours with no aggressive behavior - but , the second Waffles comes out to explore - Frannie chases her and bites her neck 
So I thought Frannie likes her, but I guess not
Do you think it might change after Waffles gets spayed ? or am I doing the whole introduction wrong ? ANY input would be greatly appreciated
Thanks !!
