The Ostermiller family says their cat was completely normal until three days after it gave birth to kittens. But it soon became defensive, and the family says it tried to kill them.
It began last week on Tuesday at about 5:30 a.m. The Ostermillers were sleeping when they heard a sound.
"All I heard was rrwwwrrrr hisss," Jackie Ostermiller said.
Jackie woke up and saw her cat, Renesmee, (named after the Twilight character) panicking. Jackie thinks a male cat had wandered by outside the home and Renesmee was protecting her kittens.
Jackie went to grab her cat to stop her from bolting out a hole in the screen door. That's when the kitty made its move.
"I was being mauled literally for the kill. She had got a hold of my nose first, my face first, my arms - I was literally screaming," she said.
Jackie's husband, Blaine, was able to pry the attacking feline off.
"I woke up hearing my wife scream, I didn't know what was going on until I looked over there, until I looked over there seeing (the cat) viciously attacking her," Blaine said.
But the cat had already made its mark. Jackie was left with 35 bite marks and 15 bruises.
The cat wasn't through. When Jackie was washing blood off her face, it came back and started attacking her leg a second time.
"She came at me with the deadliest eyes," Jackie said.
"I noticed she was looking at my wife with a weird look," Blaine said.
But even after this whole ordeal, the Ostermiller family hasn't turned their back on cats. They even plan on getting a new kitten soon. But they do have a word of caution.
"I want people to know how dangerous cats can be, they can turn on you in a dime. Believe it or not - cats!" she said.
Jackie feels that none of this would have happened either, if they had just spayed their cat. The family ended up giving up Renesmee to the Rexburg shelter.
It's likely that it will be put down.
