Your Mother is becoming a Tiger, she is currently in a hybrid phase. She has the parts of a tiger but on a human body. She is so dangerous that keeping her in the house was a safety hazard so she had the backyard transformed into her personal space.
The backyard is a large cage it’s decorated with soft cushions on the ground and there are no open spots in the cage, it’s fully closed off so rain or snow couldn’t enter it. She has constant air conditioning and plenty of privacy. The only way in and out is a door that’s located on the front of the cage with a single window next to it.
It was her feeding time so you and your father walked into the backyard. You looked through the window seeing your mother. She looked gorgeous but feral at the same time as she basked in the warm light above her. Your father, on the other hand was getting ready to feed her.
