I have several cans of cat food (Innova, Nutro, and Whiskas) that have
been in the cupboard for quite a while (I now feed Wellness). These are
all well past the "best by" dates. Should I throw them away or give
them to a shelter?

Mike,
The food is probably fine. The only changes in cat food over time
of any consequence is a drop in palatability. If the cans are exposed
to changing temperature cycles or freezing you can get what is called
synerisis where the water separates from the loaf of food and then
palatability will decline more rapidly. There is certainly nothing
harmful about expired cans. (assuming of course the seal is still
intact and there is no "bulge" in the can lids)
