When two cats fight, the outcome is rarely pretty for either side. However sometimes one cat emerges victorious and the other cat sulks away a loser. In the case of Felix the cat, a rival chased Felix near the river’s edge and then gave one final push to know Felix into the water.
Fortunately a passerby reached in and rescued Felix. Now that Felix is back on dry land and presumably better, you can expect this rivalry between the two cats to escalate. It’s a good thing neither cat has access to nuclear weapons or we’d all be in trouble by now.
