What caliber does this "Advantage" come in?

12ga?
20ga?
.410?


The trick with cat's is communication.

Cat's think that Humans are stupid. Thickest monkeys ever to fall out of a tree. Only a dumb monkey/human thinks that furry = harmless & cute. Cat's await the day when some Monkey Human Mug invents the paw operated can opener and T.V. remote control.

Then it's extermination time, Monkey Boys.........


You have to "communicate" certain facts of life to them. Like exterminate us and our allies The Canines will avenge us.
