Your pet isn't what it seems
They had anxiety issues, didn't sleep well, often awakened in tears. After years of war, living in peace was very hard. They left to get groceries and returned to find a shocking discovery. A massive tank was in their apartment with an odd arrangement. One side was the life support system for the tank, the other side was a large metal box, almost as tall as they were, attached via wide metal tubes. Inside the tank was a huge octopus, or what seemed to be an octopus. Still, it was a lovely arrangement, and caring for the octopus, making sure the water was clean, there was plenty of food, soft music, was not only easy, but soothing. However, during a rain storm, when thunder set off the PTSD, another surprise occurred. The octopus could talk, and, acting as a therapist, was trying to calm them down.
