LOUISVILLE, Ky. (WDRB) -- A Portland, Ore. family is saying goodbye to the family cat that once held them hostage.

Lux's owners called 911 last week when the family says the cat scratched their infant son after he pulled on his tail. The boy's father reportedly kicked the cat, who went crazy with rage.

The family first said they would treat the cat with therapy, but have since taken him to an animal shelter.

Experts there say there is an explanation for the cat's behavior.

"This is a very shy, somewhat high-strung cat," said Karen McGill, an animal care technician. "He's in a very high-stress situation. Apparently they live near a train station, so there's loud, noisy trains going by. They have a small child who is learning to crawl, is very vocal. Cats like this, they can only take so much."

The baby was not hurt and the family is not commenting on their decision.

WDRB News reported on the 911 call last week, shortly after it happened. Teresa Barker says the cat scratched her 7-month-old in the face, and when he was kicked for that, everything changed.

The family grabbed the baby, their dog and ran to the back bedroom. That's when they called 9-1-1.

"He's charging us," one of the family members said on the 911 call. "He's at our door. Our bedroom door."

A moment later, the sound of a cat screeching wildly can be heard on the recording.

"Did you hear it?" one of the family members says. "That was the cat!"

"One moment, okay?" the dispatcher replied. "Yeah, I hear him. Keep your door shut, okay?"

Police used a snare and were able to get the cat behind bars in its crate. The family is talking about getting rid of the cat.

The baby is okay.
