It is incredibly rare for cats and dogs to become acclimatized to each other in such a short period of time. They became so attached to each other that the owner decided it was time to play a prank, to pretend separating the two best of friends and see their hilarious actions unfold. As cruel as it is, we do believe that the owner was in the right to prank its pets because their reactions are clearly worth the effort.
They are like two peas in pod, inseparable. Their mutually shared bond cannot be shaken and they love each other to bits. They complete each other's lives and the gaping hole in their heart seems to have been filled with love of each other. Here's hoping that the two of them get to have more fruitful years in the future.
