Wild Cohort + Natural Bond

[Snig]

Just wondering if these two feats work together?

Unfortunately, no. Natural Bond only works with animal companions, and Wild Cohort gives you an animal cohort, which different than an animal companion (though functionally similar). Per the Wild Cohort feat description (http://www.wizards.com/default.asp?x=dnd/re/20031118a):

Special: Druids and rangers who take the wild cohort feat gain an animal cohort in addition to their animal companion. Although the two abilities are similar, they follow different sets of rules and must be tracked separately.

EDIT: When you have relatively straightforward rules questions like this one, you may find the stickied D&D Q&A thread (http://www.giantitp.com/forums/showthread.php?t=285715) helpful.
