If you feed your cat, it won't eat. There may be several reasons:
There may be irritating spices in bacon, and the smell will make cats stay away.
The cat is not hungry. Cats don't have much enthusiasm for food when they are not hungry.
Cats may not really be completely wandering animals, or they may just be pet cats who can go out freely and raise their own animals within a free range. Pet cats live in a better environment, are picky about food, and don't accept food that they are not used to eating and haven't touched.
