What is the likelihood of this cat getting swallowed up by the dog? Zero. The dog is well fed and has no incentive to expend its energy into eating something which will net no positive energy at the end. From the looks of it all, the cats are still young and need to be looked out for. They were a result of a botched pregnancy and their mother died not too soon after.
Fortunately, they were able to find their new home and the dog worked as their mother. The three of them continue to support each other through thick and thin. Here's hoping that their friendship continues through to the very end without any hiccups. That bed does look a tad bit too uncomfortable, we feel that the owner should purchase a better one for them.
