Do what no other dog has done before. Go on a quest beyond all other quests. Do the amazingly amazing. Befriend the household cat. Something no other dog in living memory has done. Yep, that's your objective in this small, yet challenging game.
Is the family cat friendly enough? Will the cat put aside its hatred for your dog-ugly face? Can you put aside your need to eat the cat? All these questions and many more will be answered once you begin the adventure.
Move around, jump around, do the usual dog thingies in the house. But remember your ultimate goal... yesh, the cat. Fail at that, and you fail at all things. No point going on even. The cat needs a friend... and given your inate ugliness, so do you. Go on, put aside eons of prejudice and make friends with the cat.
