You noted a while back that all the species stuff tends to turn into gender stuff - which means you need to read Man-Kzin Wars. The Kzin are big growly tigerlike aliens from Larry Niven's Known Space universe; they started out as mercenaries, got access to Future Technology, and proceeded to genetically engineer themselves to match their own cultural biases, which resulted in gratuitously aggressive males and IQ-sub-70 females. Man-Kzin Wars is spread out over a bunch of shorts and novellas by various authors bundled into individual books - you may have seen about a dozen of them on my bookshelf when you visited last. So there's a lot of material to choose from, especially if you include a piece of smutty fanfiction that made Larry Niven's head explode.


Also: yaaaaaay you have kitties! Good luck with all of the Cat Stuff and Fox Stuff. <3 (http://www.pendorwright.com/other/The_Only_Fair_Game.html)
