The interspecies cold war is heating up in this household, and this tortoise is clearly the aggressor.
It's unclear precisely what the belligerent reptile hopes to accomplish. Does he presume to establish dominance over the home's rightful leader, Fred the cat? Even the family dog looks like he knows his place.
Initially unperturbed by the tortoise's attempts to shell-shock him, Fred caves and tries to bat at his challenger, only to be met with a paw-full of carapace. Is the best offense a good defense? What if the odds were evened a bit?
In any case, the tortoise fared far better than the average baby against his feline opponent.
